make the pkg-config error message more precise

while the meaning of the error message is actually pretty obvious from
the context, some people apparently expect an equivalence with their
package manager's terminology.

do not look for mkspecs/ directories in project trees

this pretty surprising behavior would interfere with building the
examples from an installed qt tree with qmakes from other qt builds.

.qmake.conf (and .qmake.cache) files provide a possibility to explicitly
"anchor" project roots, so there is no point in having a second, even
more magic way to do it.
