(or quickpkg) Or is it the 8 hours that you're concerned about? If so, sounds like an overnight job.
When looking at this on my system I found that lto use flag was not in gcc - so i have broken my config at some stage. (im whilelisting packages for lto, not blacklisting, so the config is a little different). Rebuilding 4.7.3 now to try it out.
