Alex Rønne PetersenandRich Felker 6af4f25b89 s390x: manually inline __tls_get_addr in __tls_get_offset 
Calling __tls_get_addr with brasl is not valid since it's a global symbol; doing
so results in an R_390_PC32DBL relocation error from lld. We could fix this by
marking __tls_get_addr hidden since it is not part of the s390x ABI, or by using
a different instruction. However, given its simplicity, it makes more sense to
just manually inline it into __tls_get_offset for performance.

The patch has been tested by applying to Zig's bundled musl copy and running the
full Zig test suite under qemu-s390x.
