[gtkada] Patch: Fix PRJDIR, libdir and exampledir.

Correct of course. The grep was before I reviewed the use of DESTDIR
(following your email). Now we have:

grep libdir Makefile*
Makefile:libdir=${prefix}/lib
Makefile:		--lib-subdir=${libdir}/gtkada/gtkada_gl.$(@F) \
Makefile.in:libdir=@libdir@
Makefile.in:		--lib-subdir=${libdir}/gtkada/gtkada_gl.$(@F) \

That doesn't really matter, that's not installed anyway, these are old
examples.
