For one, because in the Autoconf package,
  make check

invokes tests that make use of this feature.  See
autoconf/lib/freeze.mk:check-forbidden-patterns and

Since the workaround is so easy in this case (./configure GREP=grep),
and I'd call IRIX an, umm, rather less important target, but most of all
since Autoconf has documented for a long time now that AC_PROG_GREP
checks for multiple -e, I would vote for keeping it that way.

Hope that helps.
