  1. 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

  2. enable test coverage for armv8-linux-musleabihf 

     * fix libc prototypes of offsets to have correct integer sizes and
   signedness. This gets all behavior tests to pass for
   armv8-linux-musleabihf
 * fix linux mmap syscall to have correct integer size and signedness
   for offset
 * disable failing armv8-linux-musleabihf std lib tests. See 3289. I
   suspect compiler-rt issue. Note these tests fail with this target
   triple regardless of whether musl is actually linked (-lc).
