Absolutley *not* .

For per-package tool support:

	USE_GNU_TOOLS=sed grep
	USE_GMAKE=yes

In more general cases: if such basic and simple utilities like cat(1) and
echo(1) are not compatible on your system, I'd rather consider upgrading
them, changing defs.IRIX.mk or /etc/mk.conf . Also, comments in mk/tools.mk
should be useful for you. Remember, if specific package needs GNU version of
[whatever], place it in package Makefile. If your whole system seems
incompatible, don't touch package's Makefile, fix it on a lower level.
