In most cases that is not necessary. You might be able to clean things up a
bit, but keeping it as it is should not hurt.
There are a few exceptions:
e.g. dhex has "-I/usr/include" (I think) in its default CPPFLAGS.
$(CROSS_ENV) does not set this anymore so I had to explicitly add
CPPFLAGS="" to overwrite the default.
