libtool-1.3.5 patches

[Dennis Haag]

First of all, thanks for your work to get GNU going on Darwin. 

Secondly, even though I work as a contractor at Apple this communication is
strictly personal and in no way reflects any official opinion, statement,
or endorsement by Apple Computer, Inc. yada yada yada....

I applied the libtool-1.3.5 patch to get libtool to work with Darwin/Mac OS
X (10.0.3). There was a slight problem. It would detect that it could
create shared libraries but then fail with the message:

*** Warning: the command libtool uses to detect shared libraries,
*** /usr/bin/file, produces output that libtool cannot recognize.
*** The result is that libtool may fail to recognize shared libraries 
*** as such.  This will affect the creation of libtool libraries that 
*** depend on shared libraries, but programs linked with such libtool
*** libraries will work regardless of this problem.  Nevertheless, you
*** may want to report the problem to your system manager and/or to
*** address@hidden

The ltconfig is checking a file that at least in Mac OS X 10.0.3 is a
symlink and not a dynamic library, so the test (if eval $file_magic_cmd
\$file_magic_test_file 2> /dev/null | egrep "$file_magic_regex") failed. I
changed it to point to the file instead of the symlink and it worked
beautifully. Here's a diff of what I did to fix the problem.
