I think musl will need an equivalent of strip avoidance: https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-libs/glibc/glibc-9999.ebuild#n1202
As a workaround you can rebuild cross-musl package with FEATURES=nostrip to get working objects.
was this fixed in musl-1.2.0?
If you see no activity in the bug and no equivalent of: # Avoid stripping binaries not targeted by ${CHOST}. Or else # ${CHOST}-strip would break binaries build for ${CTARGET}. is_crosscompile && dostrip -x / in the ebuild then probably not. Especially given that ebuild is EAPI=6.

To be able to reproduce it you need your host binutils built with USE=-multitarget.
