i386: Disable check_consistency for GCC 5 and above [BZ #25788]gentoo/glibc-2.30-10gentoo/2.30
check_consistency should be disabled for GCC 5 and above since there is
no fixed PIC register in GCC 5 and above. Check __GNUC_PREREQ (5,0)
instead OPTIMIZE_FOR_GCC_5 since OPTIMIZE_FOR_GCC_5 is false with
-fno-omit-frame-pointer.
(cherry picked from commit f90a7e96df87edadd503a0a32aa70fb97c55a044)
