Only add flags to CFLAGS_FOR_BUILD if $CC and $CC_FOR_BUILD are the same.
Otherwise, just because a flag is appropriate for $CC, that doesn't
necessarily mean it's appropriate for $CFLAGS_FOR_BUILD.
(We don't use CFLAGS_FOR_BUILD for many things, so it's probably not
worth making a lot of effort to throw all the warning flags into it if
we're cross-compiling; we *do* throw them in for native compilation,
which is what most developers use and test with, so that should be
sufficient to let the warnings catch problems with the build tools we're
building.)
