Log:
PR82396 workaround

r253236 broke AArch64 bootstrap.  This is a temporary workaround that
disables qsort checking in the scheduler to enable continued development
and testing on AArch64.  This will be removed once the autopref scheduling
code has been fixed.

        * haifa-sched.c (ready_sort_real): Disable qsort checking.
