FWIW: I’m on gcc 6.4.0, the compiler flags used to build Lilypond are:
-march=native -O2 -fomit-frame-pointer -pipe -ggdb
AFAIR, -O2 is the default on a Gentoo system.

Last December the maintainers made a change which required me to rebuild
the entire system:

“Where supported, GCC will now build position-independent executables (PIE)
by default.”

There is 2.19.80 available in the repository, so I could give it a try easily.
