Change a build-attribute REQUIRES check to use supported not requested.

Change a build-attribute REQUIRES check to use supported not requested.

Previously it would print both the targets compiled-in and the
target requested on the commandline, but we really only care
about what's compiled-in.

This comment's indentation is weird (but was also weird before) - make sure
clang-format agrees with it?

Hmm, clang-format seems to force the comment to stick with the #define indent

I moved the comment before the if (Stream), as one weird trick to get better
indenting.

No problem either way, just want to avoid the "next guy" getting an unexpected
formatting change from clang-format.
