On my 32-bit machines I have...
FLAGS="-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe
-fno-unwind-tables -fno-asynchronous-unwind-tables"
CXXFLAGS="${CFLAGS}"
See http://comments.gmane.org/gmane.linux.busybox/36695 for why I
include "-fno-unwind-tables -fno-asynchronous-unwind-tables". Would I
have to rebuild system and world without...
-fomit-frame-pointer -fno-unwind-tables -fno-asynchronous-unwind-tables
...to have debug data available?
