libgomp: Use sizeof(void*) based checks instead of looking through $CC $CFLAGS for -m32/-mx32
Some gcc configurations default to -m32 but support -m64 too. This patch
just makes the ILP32 tests more reliable by following what e.g. libsanitizer
configury does.
2021-03-04 Jakub Jelinek <jakub@redhat.com>
* configure.ac: Add AC_CHECK_SIZEOF([void *]).
* plugin/configfrag.ac: Check $ac_cv_sizeof_void_p value instead of
checking of -m32 or -mx32 options on the command line.
* config.h.in: Regenerated.
* configure: Regenerated.
