MIPS: Accept arguments for -mexplicit-relocs
GAS introduced explicit relocs since 2001, and %pcrel_hi/low were
introduced in 2014. In future, we may introduce more.
Let's convert -mexplicit-relocs option, and accpet options:
none, base, pcrel.
We also update gcc/configure.ac to set the value to option
the gas support when GCC itself is built.
gcc
* configure.ac: Detect the explicit relocs support for
mips, and define C macro MIPS_EXPLICIT_RELOCS.
* config.in: Regenerated.
* configure: Regenerated.
* doc/invoke.texi(MIPS Options): Add -mexplicit-relocs.
* config/mips/mips-opts.h: Define enum mips_explicit_relocs.
* config/mips/mips.cc(mips_set_compression_mode): Sorry if
!TARGET_EXPLICIT_RELOCS instead of just set it.
* config/mips/mips.h: Define TARGET_EXPLICIT_RELOCS and
TARGET_EXPLICIT_RELOCS_PCREL with mips_opt_explicit_relocs.
* config/mips/mips.opt: Introduce -mexplicit-relocs= option
and define -m(no-)explicit-relocs as aliases.
