Add auxv parsing to the architecture vector.

Browse Source 
Necessary to fix parsing auxv entries from core files on systems that use
the layout specified by ELF instead of the incompatible variant used by Linux.

gdb/Changelog:

        * gdbarch.sh (auxv_parse): New.
        * gdbarch.h: Regenerated.
        * gdbarch.c: Regenerated.
        * auxv.c (target_auxv_parse): Call gdbarch_parse_auxv if provided.
