So only Fuchsia would be supported, Linux would still need external ctrbegin.o/crtend.o (from gcc by default, but for projects like https://blogs.gentoo.org/gsoc2016-native-clang/ there still won't be any good solution).

Btw, do you have a crtfastmath.o on Fuchsia ? It's optionnal for clang, but if it is missing performance could be slower than Linux for programs using -ffast-math.
