fix usage of "empty" libraries
a header-only library in a default location would produce no variables
at all, making it appear undefined. fix this by forcing the writeout of
the QMAKE_LIBS_* variable, and use its definedness (rather than
non-emptiness) as a signifier.
this works for both QMAKE_USE and configure tests'/libraries' 'use'
entries.
