This reverts commit e81d7fd1e5.
The insane logic that prepends the version number of a lib to
TARGET_EXT instead of appending it to TARGET breaks every vcxproj
with a library version.
Fixing this properly will require much more work and testing on all
supported Windows platforms.
Forward-port of 8869b3b3 in qt/qt.git.
