[PATCH] Allow -gsplit-dwarf for all ELF targets, not just Linux

[Joerg Sonnenberger]

We could add a toolchain flag whether objcopy is supposed to exist. PS4 could set that to false, everything else to true. That would allow at least a proper error message for the PS4 case and whoever else cares. I think silently failing here is very bad as the option changes the behavior of clang (it is supposed to create another output file after all).
