Cross building tools broken on MacOS X

[RadosÅaw Kujawa <radoslaw.kujawa%c0ff33.net@localhost>]

Recent changes to lint are problematic at least on MacOS X:

$ ./build.sh -m amiga -U tools
(...)
#      link  lint1/lint1
cc -O -no-cpp-precomp -I/Users/rkujawa/Downloads/src/usr/src/tools/compat/obj

Undefined symbols:
  "___arraycount", referenced from:
      _initmtab in ops.lo
ld: symbol(s) not found
collect2: ld returned 1 exit status

I believe that this happens due to the fact, that MacOS X does not provide 
___arraycount macro, and somehow this macro is not included from 
tools/compat/compat_defs.h .
