poky-tiny: Use musl for default system C library
poky-tiny is reference for smallest footprint distro that can be
generated using yocto project infrastructure. Therefore switch to using
musl which gives the smallest footprint with a lot of extra stretching
for adding new package if needed, core-image-minimal for qemux86 comes
out to be 716K ( rootfs only ), boot tested on qemux86/poky-tiny
