Are BOOT_CFLAGS, CFLAGS_FOR_TARGET, and CXXFLAGS_FOR_TARGET necessary and sufficient?

I read http://gcc.gnu.org/install/build.html but wasn't completely enlightened.
If I'm building C and C++ (i.e. configuring with
--enable-languages=c,c++) and I want to build gcc, g++, and libstdc++
with -O3 instead of the default (which I believe is -g -O2), is this
correct:
make "BOOT_CFLAGS=-O3" "CFLAGS_FOR_TARGET=-O3" "CXXFLAGS_FOR_TARGET=-O3"
Or should I add/remove variables?
Thanks,
