Using USE_LANGUAGES

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

Some autoconf scripts seem to invoke c++ and f77, even though the
application doesn't use either language.  This causes a warning message
from pkgsrc suggesting that I add those languages to the USE_LANGUAGES
variable.  Should I listen?
