Makefile generation: How to prevent QMake from setting compile flags

I am overriding some QMAKE variables with my own values. However, when I check the makefile QMake generated, I can see that QMake is putting some extra values in it and I can't find a way to prevent that, or to "clean" a variable.

Here is a sample of my project file :

marvell_release {
    QMAKE_CC=/usr/local/arm-marvell-linux-gnu/bin/arm-marvell-linux-gnu-gcc
    QMAKE_CXX=/usr/local/arm-marvell-linux-gnu/bin/arm-marvell-linux-gnu-g++
    QMAKE_CFLAGS=-pipe
    QMAKE_CXXFLAGS=-pipe
    QMAKE_LINK=/usr/local/arm-marvell-linux-gnu/bin/arm-marvell-linux-gnu-ld
    QMAKE_LFLAGS=
}

And here is what QMake generated from the project file :

CC            = /usr/local/arm-marvell-linux-gnu/bin/arm-marvell-linux-gnu-gcc
CXX           = /usr/local/arm-marvell-linux-gnu/bin/arm-marvell-linux-gnu-g++
DEFINES       = 
CFLAGS        = -pipe -O2 -Wall -W -fPIE $(DEFINES)
CXXFLAGS      = -pipe -O2 -Wall -W -fPIE $(DEFINES)
INCPATH       = -I/usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux-g++-64
LINK          = /usr/local/arm-marvell-linux-gnu/bin/arm-marvell-linux-gnu-ld
LFLAGS        = -Wl,-O1

As you can see, the LFLAGS variable contains two options that I didn't specify and that I would like to remove. Does anyone know how to do that, or the explanation of why are these values being appended?

Custom your own mkspec for qmake, reference could be: https://github.com/qtproject/qtbase/tree/5.5/mkspecs/devices
