libtool on darwin

[Peter O'Gorman]

While trying to figure out how best to patch libtool so it doesn't 
complain on 10.1, I ran make check with /bin/sh as bash and then as zsh.

Here are the results (cvs HEAD as of yesterday no patches applied)
bash
=====================
10 of 92 tests failed
=====================
zsh
=====================
31 of 87 tests failed
=====================

So, It looks like it is slightly screwed up on Mac OS X 10.1 unless the 
user was smart enough to change /bin/sh to something else. Anyone want 
to volunteer to fix this?

For my patch for archive_expsym_cmds, I think I'll just check if 
ZSH_NAME is set, and if it is not do anything, okay?

As for the failures with bash:
1) depdemo always fails because although libtool adds the -L for l1 and 
l2, it never adds the lib itself.
2) The static archives do not have ranlib run on them using incremental 
linking because concat_cmds contains only ':' instead of ranlib (this 
is probably not an issue "in the wild", as the command line length is 
rarely too long).

There are one or two other failures too, haven't looked too closely yet.
