This patch adds missing function declarations in several m68k-specific
libgloss source files. This helps avoid implicit declaration compiler
warnings / errors and ensures better portability.
Tested by building newlib for m68k-elf with GCC.

This _isr_vec_count=1 is prevalent in MIPS Open FGPA examples.
Looks like forcing _isr_vec_007 in to the link was a mistake
and we always intended to only include the top-level _isr_vec
symbol.

The compiler driver positions the linker script at the end of the linker
command-line, after crtend.o. As a result, any INPUT objects and archive
GROUPs introduced by the linker script end up after crtend.o. This messes up
the end-of-frame marker provided by crtend.o
This has always been a problem, but a recent binutils update to clean-up
redundant NULL markers in .eh_frame exposes it as a execution failure in
exception-handling tests. This patch re-orders .eh_frame in all linker
scripts so that the one from crtend.o is placed last.
An alternative approach would be to fix the compiler driver to put
the linker script before the ENDFILE spec.

The __inln prototype was defined as:
extern char * __inln ();
In old versions of C, this meant "this function takes an unspecified
number of parameters". This seems to have changed, as GCC 14 now
considers that the function took zero parameters.
As the code called it with one parameter, GCC would then issue an error
saying that the incorrect number of parameters was passed.
Address this issue by changing the prototype of the __inln function.

The large code model assume the data may far away from the code, so we
must put the address of the target data wihin the `.text` section,
normally we will just put within the function or nearby the function to
prevent it out-of-range.

When building newlib for multicore environments we specify __OR1K_MULTICORE__
which switches the build to allocate one struct _or1k_reent per CPU
dynamiocally.
This was using a strange definition of (*_or1k_reent)[], and causing
the following compiler error:
./gnu-toolchain/newlib/libgloss/or1k/impure.c: In function ‘_or1k_reent_init’:
./gnu-toolchain/newlib/libgloss/or1k/impure.c:121:21: error: assignment to ‘struct ..
121 | _or1k_reent = (struct _or1k_reent*) _sbrk_r(0, memsize);
|
Fix this compiler error by changing the or1k_reent definition to a pointer
to structs.

Stub function for _getentropy is presented in libnosys and it is
not presented in libgloss libraries for ARC. When libstdc++ is
built it detects that _getentropy is presented in the default
libgloss library (libnosys). However, then GCC fails to link
applications with another libgloss libraries like nSIM, HostLink,
boards, etc. because of missing _getentropy stub in corresponding
libraries.
Here is an example:
$ cat getentropy.cpp
#include <unistd.h>
int main () {
unsigned i;
::getentropy(&i, sizeof(i));
return 0;
}
$ arc64-elf-g++ -mcpu=hs6x -specs=nsim.specs getentropy.cpp
...
... undefined reference to `_getentropy'
collect2: error: ld returned 1 exit status
Thus, it is necessary to add _getentropy stub to all ARC
libgloss libraries to prevent errors while building even
simple C++ programs.

In my build the below are treated as error now and causing failures. I
have described the fixes of each warning below.
In newlib/libc/sys/or1k/mlock.c:
CC libc/sys/or1k/libc_a-mlock.o
newlib/libc/sys/or1k/mlock.c: In function ‘__malloc_lock’:

This patch adds prototypes for functions or1k_critical_begin and
or1k_critical_end to suppress the warning, inline with what we do for
or1k_sync_cas.
In libgloss/or1k/or1k_uart.c:
libgloss/or1k/or1k_uart.c: In function ‘or1k_uart_set_read_cb’:
libgloss/or1k/or1k_uart.c:163:25: warning: passing argument 2 of ‘or1k_interrupt_handler_add’ from incompatible pointer type [-Wincompatible-pointer-types]

In file included from libgloss/or1k/or1k_uart.c:19:

97 | or1k_interrupt_handler_fptr handler,
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~
The public API is ‘void (*)(void *)' for our interrupt handlers. The
function _or1k_uart_interrupt_hander is the internal default
implementation of the uart IRQ handler and it doesn't use the data
argument.
This patch updates the _or1k_uart_interrupt_handler argument type from
uint32_t to void* allowing the function prototype to match the required
prototype.
If we did have a 64-bit implementation it would be an ABI issue. But,
there never has been one, or1k is only 32-bit.
In libgloss/or1k/interrupts.c:
libgloss/or1k/interrupts.c: In function ‘or1k_interrupt_handler_add’:
libgloss/or1k/interrupts.c:41:52: warning: assignment to ‘void *’ from ‘long unsigned int’ makes pointer from integer without a cast [-Wint-conversion]
41 | _or1k_interrupt_handler_data_ptr_table[id] = (uint32_t) data_ptr;
| ^
The table _or1k_interrupt_handler_data_ptr_table is an array of void*
and data_ptr is void*. There is no need for the cast so remove it.
In libgloss/or1k/sbrk.c:
libgloss/or1k/sbrk.c:23:29: warning: initialization of ‘uint32_t’ {aka ‘long unsigned int’} from ‘uint32_t *’ {aka ‘long unsigned int *’} makes integer from pointer without a cast [-Wint-conversion]
23 | uint32_t _or1k_heap_start = &end;

This patch adds a cast, which is safe in or1k as the architecture in
32-bit only. But this code would not be 64-compatible.

Synopsys ARCv3 ISA includes 32-bit ARC HS5x targets and
64-bit ARC HS6x targets. Both CPU families are placed
in "arc64" subdirectories as it done for GCC port.
Target name arc64 is used for historical reasons and
Synopsys ARCv3 baremetal toolchains contain multilib
configurations both for 32-bit and 64-bit families.
arc32 target name is reserved for 32-bit ARC HS5x
targets in case of non-multilib 32-bit builds.
Note that libgloss libraries for ARCv3 are compatible with
libgloss for ARCv1/2. Thus, Makefile.inc for libgloss uses
sources from libgloss/arc directory except crtX.S files.

Assembler for ARCv2 always extends the name provided by
.file directive to an absolute form.
On ARCv3 targets .file directive forces assembler to put
a provided string to DW_AT_name field as is without
extending to an absolute path. Then GDB cannot find
source files because of it.
The best way to fix this issue is just delete lines
with .file directive in .S files and let the compiler
to decide what DW_AT_name must contain. Particularly,
the compiler fills this filed by an absolute path to
a .S file because only absolute paths are used in
toolchain's build process.

According to GCC documentation for ARC, a function marked with
the long_call attribute is always called using register-indirect
jump-and-link instructions, thereby enabling the called function
to be placed anywhere within the 32-bit address space.
exit_halt function is provided by crt0.S and it's used
in nsim-syscalls.c. Thus, we want to ensure that a linkage
