QmakePM: Fix false positive warning for incompatible compiler

Browse Source 
Some users set 'QMAKE_CXX = @echo $< && $$QMAKE_CXX' to prettify the
compiler output.

Another useful case for "incompatible" compiler is ccache, or other
compiler wrappers.

To eliminate warnings for these cases, pick the last value of QMAKE_CC/
QMAKE_CXX, excluding flags, and compare it against the configured toolchain.
