cfg.mk: Add checks for 'u_int'.

[Collin Funk]

At some point someone added syntax-checks to fail if old BSD types
where used:

      u_char -> unsigned char
      u_short -> unsigned short
      u_long -> unsigned long

But they forgot to do u_int. Patch 0001 adds one for u_int and patch
0002 removes them.

IIRC Glibc and MinGW define these, so it would work fine in 99% of
places.
