upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
mtree is only used for cross compilation at this point. Also, the
required patches to make it compile on Minix cripple it probably
enough to make it unusable anyway.
