Fix developer build with -Werror

The group parameter is only used when cross-compiling, mark it as unused
otherwise. This is noticeable in the cmake branch because there we build
qmake with cmake and apply the same warning flags, as opposed to the
bootstrapped qmake build when using ... qmake.

The cache file parameter in qmake is unused and the
mustEnsureWritability is only used on Windows.
