Created attachment 548110 [details] output of emerge --info my emerge --info its from a qemu-chroot, but that shouldn't matter.
here's the problem: USE=clang pulls in ld.ldd as the linker to use, but mozcoreconf-v6 has some optimized linkerflags for arm enabled which are only compatible with ld.bfd same breakage would happen when ld.gold is choosen, but here its only -Wl,--reduce-memory-overheads being incompatible. it should be for ld.bfd: append-ldflags -Wl,--no-keep-memory -Wl,--reduce-memory-overheads for ld.gold: append-ldflags -Wl,--no-keep-memory for ld.ldd: <empty> ppc64 has a similar optimization for linking, so it should be changed as well. Now, since mozcoreconf-v6 already includes toolchain-funcs, I thought of something like: if use arm; then if tc-ld-is-bfd ; then append-ldflags -Wl,--no-keep-memory -Wl,--reduce-memory-overheads elif tc-ld-is-gold ; then append-ldflags -Wl,--no-keep-memory fi fi (there is no check for tc-ld-is-ldd in the eclass) I already tried to get my head around this in a github pullrequest, but ever failing to solve the riddle: https://github.com/gentoo/gentoo/pull/9992 only solution so fare is to remove the whole part for the case of using clang, but that's no proper solution.
Silly me didn't properly read through the toolchain-funcs eclass. There is no tc-ld-is-bfd neither, only tc-ld-is-gold and its reversion ofc to solve this. I'll ask toolchain if they are able and willing to add detection for bfd or ldd, or both, to the the eclass.
