[cfe-dev] --split-dwarf silently fails on non-Linux platforms

[Eric Christopher]

Mostly that the only platform we knew it worked on was Linux and didn't
want to make it error out. We can make it not error for all elf targets for
sure if you'd like to give it a go. Needs a relatively recent binutils and
GDB (currently no lldb support).
