Kees Cook ed14ef08c5 ARM: 8958/1: rename missed uaccess .fixup section 
commit f87b1c49bc upstream.

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.
