It appears like gmp doesn't play nice with musl hosts? a musl target is
fine allowing a cross environment to work but not a pure musl evnironment
or specifying musl as the host.

I created a cross compiler successfully but using the cross compiler to
"recreate itself" hasn't worked when rebuilding gmp as a part of the
process. It could be me, everything up to this point has been apparently
but i was hoping someone could chime in and let me know if they have
compiled gmp on a native musl system or if it requires a patch i missed or
some gnu code?

thanks,
stephen
