If you see that big a difference, you do a lot of cross-file calls in
tight loops. This means you would greatly benefit of compiling with -flto
instead. GCC doesn't allow linking flto objects from even slightly
different compiler versions though as gimple format is not considered
stable, so shipping precompiled static objects is no good.
So what about shipping source instead so the user can optimize the heck out
of it?
