I can explain it easily: LTO is effectively an experimental feature in Clang right now. (Ditto GCC, but GCC was eliminated in Xcode 5). Both compiler teams' test suites for it consist more or less entirely of building Firefox with it and if no smoke comes out of the computer they mark it as "success". Trying it on MAME is basically taking your life into your own hands.
