I believe so, yes. See configure.ac:ACX_ELF_TARGET_IFELSE, from Dave's
lto-coff patch that I've built upon:

"# On non-ELF platforms, LTO must be explicitly enabled."

However, that could be changed of course. For the moment, I would
prefer to keep this, though, until we have some proper testing of
non-ELF LTO on real applications (things like your big c++ app) before
it is enabled by default.

Ciao!
