Found when attempting to build binutils on sparc sunos-5.8 where
sys/byteorder.h defines _BIG_ENDIAN but not any of the BYTE_ORDER
variants. This patch adds the extra tests to cope with the old
machine, and tidies the header a little.
include/ChangeLog:
* plugin-api.h: When handling non-gcc or gcc < 4.6.0 include
necessary header files before testing macros. Make more use
of #elif. Test _LITTLE_ENDIAN and _BIG_ENDIAN in final tests.

This is one part of the fix for PR109128, along with a corresponding
binutils's linker change. Without this patch, what happens in the
linker, when an unused object in a .a file has offload data, is that
elf_link_is_defined_archive_symbol calls bfd_link_plugin_object_p,
which ends up calling the plugin's claim_file_handler, which then
records the object as one with offload data. That is, the linker never
decides to use the object in the first place, but use of this _p
interface (called as part of trying to decide whether to use the
object) results in the plugin deciding to use its offload data (and a
consequent mismatch in the offload data present at runtime).
The new hook allows the linker plugin to distinguish calls to
claim_file_handler that know the object is being used by the linker
(from ldmain.c:add_archive_element), from calls that don't know it's
being used by the linker (from elf_link_is_defined_archive_symbol); in
the latter case, the plugin should avoid recording the object as one
with offload data.

Gold plugins may wish to further process an input file added by a plugin. For
example, the plugin may need to assign a unique segment for sections in a
plugin-generated input file. This patch adds a plugin callback that the linker
will call when reading symbols from a new input file added after the
all_symbols_read event (i.e. an input file added by a plugin).
