3.0.6-rko blank avail fix

[R.K. O. Ph.D. <rk...@ow...>]

As a couple of people have noticed on Sun systems the "module avail"
produced no output.  I've discovered the problem, and I'm surprised
that the code worked just fine on Linux & AIX, which is probably an
artifact of how the stack is laid out.
Anyways, just make the following change as directed by this
uniform context sensitive patch to utility.c.
A new version of modules will be uploaded next week sometime
with some other changes.
Thanks for all those that raised the alert.
