remove QMAKE_<lib>_SUFFIX support

this feature was added with a dubious commit message a decade ago, was
undocumented, and there are no public traces of it being used.

if i had to guess what it was meant for: to be able to consistently use
-lfoo throughout a project and centrally (e.g., in .qmake.cache) choose
to use foo<bar> (bar possibly being "d") instead. however, more explicit
methods are being used instead, including in qt itself.
