from IRC discussion with Arsen: Adding "unset AR AS CPP NM STRIP RANLIB OBJCOPY STRINGS OBJDUMP READELF ADDR2LINE LD CC CXX" to the top of pkg_setup function in /var/db/repos/gentoo/sys-libs/musl/musl-1.2.4-r2.ebuild fixes the issue. CC="clang" seems to be hardcoded in the llvm profile.
update: crossdev build finishes, but produced toolchain doesn't seem to work: $ emerge-powerpc64-unknown-linux-musl -avu app-editors/nano ... checking for native build linker-flags... -Wl,-O1 -Wl,--as-needed -Wl,-z,pack-relative-relocs -Wl,--as-needed checking for native build linker-libraries... checking if the build-compiler "gcc" works... no configure: error: Cross-build requires two compilers. Use --with-build-cc to specify the native compiler.
