LoongArch: adjust the default of -mexplicit-relocs by checking gas feature
The assembly produced with -mexplicit-relocs is not supported by gas <=
2.39. Check if the assembler supports explicit relocations and set the
default accordingly.
gcc/ChangeLog:
* configure.ac (HAVE_AS_EXPLICIT_RELOCS): Define to 1 if the
assembler supports explicit relocation for LoongArch.
* configure: Regenerate.
* config/loongarch/loongarch-opts.h (HAVE_AS_EXPLICIT_RELOCS):
Define to 0 if not defined.
* config/loongarch/genopts/loongarch.opt.in
(TARGET_EXPLICIT_RELOCS): Default to HAVE_AS_EXPLICIT_RELOCS.
* config/loongarch/loongarch.opt: Regenerate.
