```
musl [PATCH] arm: fix setjmp and longjmp asm for armv8-a

From: Szabolcs Nagy <szabolcs.nagy@arm.com>

armv8 removed the coprocessor instructions other than cp14, so
on an armv8 system the related hwcaps should never be set.

new llvm complains about the use of coprocessor instructions in
armv8-a mode (even though they are never executed at runtime),
so ifdef them out when musl is built for armv8.

<dalias> i think the patch looks ok
