two Mac guile patches

[Ken Raeburn]

Two patches here, both relating to the fact that the GNU "libtool"  
package is installed as "glibtool" (both in the main OS and in  
macports; haven't checked fink), and "/usr/bin/libtool" is a different  
tool, from Apple.

The autogen script wants to display a version number from libtool  
before it'll run autoreconf, and will error out if it can't do so.

The gdb-uninstalled-guile script assumes it can find a working  
"libtool" via $PATH, and there's a "libtool" at the top of the build  
tree which is presumably the one we actually want, but uninstalled-env  
doesn't add ${top_builddir} to $PATH.  Since the libtool script is the  
only thing there we'd want to find that way, I changed gdb-uninstalled- 
guile rather than uninstalled-env.


    Fix autogen.sh for Mac OS X.

    * autogen.sh: If uname indicates that the OS is Darwin, run  
"glibtool"
      instead of "libtool" for the version number check.
