I'm looking at going with...
CFLAGS="-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe -fno-pic -fno-PIC -fno-pie -fno-unwind-tables -fno-asynchronous-unwind-tables"
CXXFLAGS="${CFLAGS}"
...and with -pic in USE. This is the mirror image of the defaults. Any
obvious problems, aside from losing a bit of security? In case you're
wondering about the "pic" USE flag...

I don't run "desktop environments"; I run useful applications
