ltmain.sh quoting fix.

[Andrew C. Feren]

I actually discovered this while compiling an other package (Ethereal)
which bundles a copy of libtool 1.4.  I've included a minimal fix to
correct the problem I was seeing and a more complete fix along with a
patch for sh.test.

The basic problem is that test "never sees" uninitialized variables
that are not quoted.

test $some_unset_var = test_case

vs

test "$some_unset_var" = test_case

in the former case you get the following error message (assuming my sh :-)
test: argument expected

First the minimal patch to ltmain.sh

ltmain.sh.patch
Description: minimal patch

Now the alternate (more complete patch)

ltmain.sh.big.patch
Description: Text Data

sh.test.patch
Description: Text Data

It just occurred to me that my test in sh.test is actually just a
generalization of the test above it.  Oh well, I'm not going to adjust
it now.  Shouldn't hurt anything to leave two tests, but the two cases
can probably be merged.
