You have overlooked that sys.mk will be processed "before any other 
file, including makefile and Makefile" (make(1)). /usr/share/mk/sys.mk 
includes already bsd.cpu.mk once at a time where CC has not been set to 
'icc'. Therefore ${_CPUCFLAGS} will be added to CFLAGS in bsd.cpu.mk. 
Afterwards you include bsd.cpu.mk twice.
