[committed] d: Update recipes for building html and pdf documentation

[Iain Buclaw <ibuclaw@gdcproject.org>]

Hi,

This patch sorts out the include directories for building the gdc docs -
we don't need to include anything from the toplevel docs directory.

The html output directory has also been renamed from /d/ to /gdc/ to
make it clearer that this is vendor-specific documentation.

Tested by building and checking pdf/info/man/html pages, and committed
to mainline.

Regards,
Iain.

	(d.html): Rename html directory to $(build_htmldir)/gdc.
