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.

this is complementary to configure's makeSpec library source type.
this should be sufficient to make QMAKE_USE += {egl,opengl,opengl_es2}
actually work, obsoleting the need for opengl.prf and egl.prf (and the
currently dysfunct openvg.prf).

Split them and add -I flags to INCLUDEPATH and -D flags to
DEFINES. Anything else gets reported as a problem and dropped.
This has the benefit that qmake will automatically use -isystem for
those paths if they lie in a system directory. As a consequence of that,
we won't get any warnings in headers located there. There are multiple
cases of glib, gtk, etc. headers producing warnings (such as enums
ending in comma). This does not fix warnings produced by use of macros
declared in system headers, though...

it's now possible to declare references which don't cause linking (or
cause only linking).
make use of this in the xcb-static library.

this makes it possible for features added via CONFIG to use QMAKE_USE*,
as default_post.prf is processed before all features in CONFIG.
