DetermineCompiler: Restore identification of MSVC with no INCLUDE or LIB
Update the change from commit c6aaaf066a (DetermineCompiler: Restore
identification of MSVC with no INCLUDE dirs, 2021-06-29,
v3.21.0-rc2~6^2) to also work with no `LIB` dirs. Add the `-c` flag to
compile an object file without linking.
