[cvs-nhc98] patch applied (hat): Portable Hat makefile:

[Malcolm Wallace]

Wed Jan 23 10:52:00 PST 2002  malcolm
  * Portable Hat makefile:
    * no need to rename .hi files, since ghc gives them the right name anyway
    * when renaming .hx files, get the original filename right
    * use 'ar' to make a library archive, not gcc!
  It really does work now - I tested it right through to completion.

    M ./src/hatlib/Makefile -16 +6
