What exactly do these numbers mean?

With "ls -l" I get

14865104 luatex-strippped (if I manually strip the binary)
15824232 luatex

If I run the normal build (without --nostrip) I get 8999388 bytes.

Luigi, what exactly does the following chunk of code do in build.sh?

if [ "$STRIP_LUATEX" = "FALSE" ]
then
    export CFLAGS
    export CXXFLAGS
fi

I don't understand why I get different results if I manually strip the
binary or if the build.sh strips it unless the binary actually gets
compiled in a different way (with different flags / different
optimization) depending on the presence of --nostrip option.
