qmake: fix lookup of .prl files for libs specified by full filename
under windows, libraries can have a numeric suffix derived from VERSION,
and (under MinGW) a unix-like "lib" prefix - neither of which .prl files
have. therefore, we had to make the back-mapping from the library to the
.prl file reverse-engineer the original TARGET's name. we verify whether
we actually got the right file by comparing the target specified inside
the .prl file with what we started from.
this fixes linking of transitive deps of static deps.
the alternative of changing the .prl naming pattern to avoid the
back-mapping was discarded, as a) it would be backwards incompatible and
b) it would break project-internal -lfoo references to versioned libs.
