Windows: Clean-up linker warnings regarding MSVCRT.lib

For debug builds we link the against the release mode libs
for C based libraries, which are technically linked against
a different CRT, which the linker will implicitly try to link.

Which results in a linker warning about mixing the debug/release CRT.

This patch prevents the implicit linking of the release
CRT in debug configurations for sub projects that had issues
with it.
