I've posted the current version of my patches in my toolchain repo:
https://github.com/richfelker/musl-cross-make/commit/3a0c9775b69ae311d89b6a9df6788d43f206cf6c
As noted in the commit message, a patch on the musl side is needed to
get actual working binaries. I'll post a version of this (not
appropriate for upstream) soon.
