[Qt-interest] Removing values from QMAKE_CXXFLAGS

[pepone.onrez]

Don't set it always, just use a conditional

i will do something like

NO_MP=yes
NO_GL=yes

//..include top level

//top level file
ifneq $(NO_MP, yes)
    QMAKE_CXXFLAGS += /MP
endif

ifneq $(NO_GL, yes)
    QMAKE_CXXFLAGS += /GL
endif
