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.
