Would you like to build more toolchains using the approach used by
LFS? Using shell scripts?

I've made a patch once to to add support for the software versions
used by LFS. That makes musl-cross-make download gcc, binutils, etc
(the same version used in LFS) and build the toolchain with it. If
you're interested I could try to recreate it.
