There is a nicer way of achieving the same thing:

CFLAGS += -nostdinc -iwithprefix include

`-iwithprefix DIR'
Add a directory to the second include path. The directory's name
is made by concatenating PREFIX and DIR, where PREFIX was
specified previously with `-iprefix'. If you have not specified a
prefix yet, the directory containing the installed passes of the
compiler is used as the default.
