PR binutils/18750
* ihex.c (ihex_scan): Fixes incorrect escape sequence in error message
and stack overflow when char is signed and \200-\376 was in place of hex
digit; also fixes \377 was handled as EOF instead of "incorrect character".
(ihex_read_section): Changed for consistency.
(ihex_bad_byte): Prevent (now impossible to trigger) stack
overflow and incorrect escape sequence handling.
* srec.c (srec_bad_byte): Likewise.
* readelf.c (process_mips_specific): Fix incorrect escape
sequence handling.

This patch changes "ld -r" not to set link_info.executable. It
removes !info->relocatable check for info->executable and adds it
for !info->executable in elflink.c.

Commit 23283c1b changed the layout of some bss style sections on
powerpc64, but neglected to add a page gap before the third PT_LOAD
segment created by this reording. Without a page gap we get two
PT_LOAD headers that overlap by one page in memory. That shouldn't be
allowed because the dynamic loader will load garbage from the first
page of the last segment over the last page of the previous segment.

* elf.c (_bfd_elf_map_sections_to_segments): Do not make a new

Missing symbol version section is a run-time problem only if it will
be referenced dynamically at run-time. We should skip the check for
locally defined symbol, which isn't referenced by shared library, when
linking executable.

For the case of MIPS n64 target and 32-bit host, the computation of
the DT_MIPS_RLD_MAP_REL tag involves sdyn->output_section->vma +
sdyn->output_offset (64-bit) being added to b (32-bit host pointer),
so losing the high part and resulting in an incorrect
DT_MIPS_RLD_MAP_REL tag, and all dynamically linked glibc tests
failing for n64. This patch fixes this (spot-tested with glibc tests;
however, I don't have a self-contained testcase for this bug).
* elfxx-mips.c (_bfd_mips_elf_finish_dynamic_sections)
<DT_MIPS_RLD_MAP_REL>: Add target address to host address
difference, not to host pointer.

Bogus assembly can hit an assertion in opd_entry_value when the symbol
referenced by a function descriptor is undefined. Worse, the code
after the assert copies unitialised memory to return the code section.
This uninitialised pointer can later be dereferencd, possibly causing
a linker segmentation fault.
* elf64-ppc.c (opd_entry_value): Remove assertion. Instead,
return -1 if symbol referenced is not defined. Tidy.

We used to generate abort messages like:
internal error, aborting at .../bfd/elf64-x86-64.c line 1554 in elf_x86_64_check_relocs
We can't cut and paste "file line ???" to GDB. This patch changes those
abort messages to
internal error, aborting at .../bfd/elf64-x86-64.c:1554 in elf_x86_64_check_relocs
so that we can cut and paste "file:???" to GDB.
