If you don't set BOOTSTRAP_CFLAGS on the build.sh command line, the tools
themselves will be built without processor optimizations and with -O
instead of -O2.  You can't fix this for the tools "make" with settings
in mk.conf, either; and "make" chews up a not-insubstantial amount of
time in the build process.
