Fix detection of QMAKE_DEFAULT{INC|LIB}DIRS for gcc cross-builds

Browse Source 
The --sysroot flag is added to QMAKE_CXXFLAGS by the gcc-sysroot
feature. However, when the makespec is reloaded, it can overwrite
QMAKE_CXXFLAGS.

Save QMAKE_CXXFLAGS before re-loading the mkspec and add it to the
value from the makespec, like we do for CONFIG.

Fixes: QTBUG-74326
