commit: https://git.buildroot.net/buildroot/commit/?id=ab990cf58a724a178dbdd55afdb520212f7197c0
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add s390x musl supported archs. Upstream musl already supports s390x[1].

Tested with qemu_s390s_defconfig:

	$ output/host/bin/qemu-system-s390x -M s390-ccw-virtio -cpu max,zpci=on -m 4G -smp 2 -kernel output/bzImage -drive file=output/images/rootfs.ext2,if=virtio,format=raw -append "rootwait root=/dev/vda net.ifnames=0 biosdevname=0" -display none -serial mon:stdio -net nic,model=virtio -net user
