Fix regression when doing a debug only build with MSVC

qt helper libs for msvc will always get a 'd' suffix for debug builds.
This is different than for MinGW, where it will only get a 'd' for
mixed debug builds in -debug-and-release scenarios (see commit
1749f9184b).

This amends d32a679, which incorrectly removed the 'd' suffix
when linking helper libs built for MSVC.
