On OS X with a framework-based build of Qt, the 'Libs:' line of the
.pc files generated by `qmake` references the framework. This requires
two separate arguments to the linker: The fixed string '-framework' and
the name of the framework (e.g. 'QtCore'). Only the latter might need
quoting. Prior to this fix, they were treated as a single argument (e.g.
'-framework QtCore'), thus always quoted because of the contained space,
and later lead to errors when trying to link a Qt framework discovered
via `pkg-config`.
