Embedded/Cross LFS make things much more complicated than you need. You can use the main LFS instructions to generate a native complier, applying these modifications: 1. $LFS_TGT needs to be $ARCH-linux-musl 2. Patch gcc every time you compile it 3. Use a non-broken version of gcc; I recommend 4.7.x 4. Of course, replace glibc with musl 5. You may need to disable some extra math/optimization libraries that come with gcc; the musl-cross build script may give you some hints. Sysroot is generally more of a problem than it solves. It's really only useful for cross-compilers where you have a complete copy of your target's /usr somewehere. Another warning: gcc does not look in /lib or /include like you would want it to without patching like LFS does for /tools.  https://bitbucket.org/GregorR/musl-cross/src/2dfead9ed81aa590a69f1e33992935da37dee931/build.sh?at=default#cl-131 -- Regards, Samuel Holland <samuel@...lland.net>
