Kees Cook 9b9996b6ee FROMLIST: rename missed uaccess .fixup section
When the uaccess .fixup section was renamed to .text.fixup, one case was
missed. Under ld.bfd, the orphaned section was moved close to .text
(since they share the "ax" bits), so things would work normally on
uaccess faults. Under ld.lld, the orphaned section was placed outside
the .text section, making it unreachable.

Fixes: c4a84ae39b ("ARM: 8322/1: keep .text and .fixup regions closer together")
