* common.opt (static-libquadmath): New option.
* gcc.cc (driver_handle_option): Always accept -static-libquadmath.
* config/darwin.h (LINK_SPEC): Handle -static-libquadmath.
gcc/fortran/
* lang.opt (static-libquadmath): New option.
* invoke.texi (-static-libquadmath): Document it.
libgfortran/
* acinclude.m4 (LIBQUADSPEC): From $FC -static-libgfortran -###
output determine -Bstatic/-Bdynamic, -bstatic/-bdynamic,
-aarchive_shared/-adefault linker support or Darwin remapping
of -lgfortran to libgfortran.a%s and use that around or instead
of -lquadmath in LIBQUADSPEC.
* configure: Regenerated.
