'make install' fails after 'make uninstall', with --enable-ltdl-install

[Bob Friesenhahn]

I just noticed something interesting while installing GraphicsMagick.

GraphicsMagick was configured with --enable-ltdl-install so that it 
installed libltdl.  After doing 'make install' and 'make uninstall', 
a 'make install' fails with this error:
libtool: install: warning: relinking 
`Magick++/lib/libGraphicsMagick++.la'
libtool: install: (cd /home/bfriesen/build/GraphicsMagick-16-modules; 
/bin/bash /home/bfriesen/build/GraphicsMagick-16-modules/libtool

ggrep: /usr/local/lib/libltdl.la: No such file or directory
/usr/local/bin/sed: can't read /usr/local/lib/libltdl.la: No such file 
or directory
Because doing the 'make uninstall' also uninstalled libltdl which 
removed the installed libltdl.la that one of the library .la files now 
depends on.
After then doing a 'make clean', the build now fails due to not 
finding -lltdl.
