Small build system issues

Hi,

Trying do to some work on the Debian package of Amaya, I found a couple
of issues.

First, about redland.
-If you build on a system on which the libraptor is installed, librdf
will try ato automatically link against it, which conflicts with
"AMAYA_RAPTOR_LIBS="../redland/librdf/.libs/librdf.a ../redland/raptor/.libs/libraptor.a"
(line 1238 of Amaya/configure.in). The attached raptor.diff forces the
librdf to use the builtin libraptor.
-When using the system-provided librdf, the build fails because of
undefined types. Apparently, when using the redland library, you're
always and only supposed to include <redland.h>. The attached
redland.diff does that. It also need the third attached patch applied
(no_librdf_internal.diff), which stops defining LIBRDF_INTERNAL when
building Amaya. I believe passing this argument becomes useless with the
other patch (and it also generated errors using the system libdrf
because it tries to include a non-distributed file).

I also noticed that some internal tools leave generated files outside of
the build directory. There are 2 different problems, one of them is in
Amaya/batch/app.c, which writes .h and .LST files in the same directory
as the source file.

Thanks for your work. Please don't hesitate to contact me for further
details or informations.
