GraphicsMagick dev updated to latest libtool

[Bob Friesenhahn]

I have updated the development version of GraphicsMagick 1.2 to use 
the latest CVS libtool (and latest released autoconf & automake). 
Testing shows that the new mult-arch support code has re-enabled the 
ability to build GraphicsMagick properly as a 64-bit application under 
Solaris 9 with GCC.  That is very good news.

I found only one glitch, and that is related to creating a libltdl 
Makefile.inc which works properly if the libltdl directory is named 
'ltdl'.  The difference between the Makefile.inc which works, and what

  libtoolize --verbose --copy --force --nonrecursive --ltdl=ltdl

produces is shown at the end if this mail.
