It appears like gmp doe= sn'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 t= he host.

You want to use a chroot or a VM with Musl if you are having th= ese
issues. Sabotage or Alpine are good options. It will save a lot of
grief. Otherwise you are doing somethnig wrong that is hard to
diagnose without much moer info.
