Subject: [PATCH] i386: Disable check_consistency for GCC 5 and above [BZ
 #25788]

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.
