Centralize PICFLAG configuration
config:
* picflag.m4: New file.
gcc:
* configure.ac (GCC_PICFLAG_FOR_TARGET): Call it.
(PICFLAG_FOR_TARGET): Substitute.
* aclocal.m4: Regenerate.
* configure: Regenerate.
gcc/ada:
* gcc-interface/Makefile.in (PICFLAG_FOR_TARGET): New.
(GNATLIBCFLAGS_FOR_C): Replace
TARGET_LIBGCC2_CFLAGS by PICFLAG_FOR_TARGET.
(gnatlib-shared-default, gnatlib-shared-dual-win32)
(gnatlib-shared-win32, gnatlib-shared-darwin, gnatlib-shared)
(gnatlib-sjlj, gnatlib-zcx): Likewise.
libada:
* configure.ac: Include ../config/picflag.m4.
(GCC_PICFLAG): Call it.
Substitute.
* configure: Regenerate.
* Makefile.in (TARGET_LIBGCC2_CFLAGS): Replace by PICFLAG.
(GNATLIBCFLAGS_FOR_C): Replace TARGET_LIBGCC2_CFLAGS by PICFLAG.
(LIBADA_FLAGS_TO_PASS): Pass PICFLAG as PICFLAG_FOR_TARGET.
Don't include $(GCC_DIR)/libgcc.mvars.
libiberty:
* aclocal.m4: Include ../config/picflag.m4.
* configure.ac (GCC_PICFLAG): Call it.
(enable_shared): Clear PICFLAG unless shared.
* configure: Regenerate.
