The morello musl libc appends the musl_git.bb recipe. The installation path and PROVIDES depend on the machine. The native libraries that go into clang resource folder are also covered. The build order is: musl-morello-native, musl-morello-libs-native, and musl-morello-target.

Add recipes that will output a Linux image and a initramfs that contains the Morello busybox and the purecap app. The glibc version can take an arbitrary Yocto image as the rootfs. The Yocto rootfs is not tested yet but can be easily done by adding an extra grub menu option.
