'make check' errors

So, far we continue to make all of our deadlines for the 3.8 release.  All
of the language translation files have been updated and I committed the
final patches today.

The next step in the release is to examine the errors resulting from 'make
check' and determine what to do about them.  On a base linux system there
is one failure resulting from bug #38236.  This won't get fixed for this
release.  The other 7 errors are with the convolution function.  The first
of these is a tolerance issue, but in the others the dimensions of the
output and expected values differ.  This is so fundamental that I'm not
sure the tests aren't wrong rather than the code.  Could someone with
Matlab run the following?

--- Code ---
a = rand (10, 10, 10);
b = rand (3, 3);
c = convn (a, b, 'full');
size (c)
d = convn (a, b, 'same');
size (d)
e = convn (a, b, 'valid');
size (e)

a = rand (10, 15, 7, 8, 10);
b = rand (4, 3, 2, 3);
f = convn (a, b, 'same');
size (f)
g = convn (a, b, 'valid');
size (g)
--- End Code ---

After resolving the conv errors, I think we need to take a look at the
other platforms--Mac and Windows--and see what failures we have there.  In
some cases it may be approriate to add ismac(), ispc() in the %!tests to
special case certain tests.
