lib/Xlt configuration

[Alexander Mai]

Just applied some patches to lib/Xlt build mechanism.

1) drop libtool-based dependency on libXt and similar.
   Unless we use new libtool which finally link share libs against some
   libfoo.la we can not use this.
2) the examples are now linked using libtool. Focus here is on
   libXlt obviously.
3) There's still a problem left currently:
   some examples fail to link/build if no libXpm is present/found.
   Those should be disabled?!
