Actually, I think that platform_defs.h needs to be symlinked into
include/xfs. that was the intent, but I bet I missed it because
the build wasn't failing and so I didn't notice that I'd failed to
put it into the the include/Makefile rule for installed headers.

Yeah, there we are - the install-dev rule has a specific install
rule for platform_defs.h as well, so it was being included in the
package builds correctly (i.e. installed in /usr/include/xfs)
without being mentioned in the HFILES definition that defines header
files to be packaged for /usr/include/xfs....

Patch below (which uncovers another issue to do with include files
on the distclean side, but is not fatal and I'll fix tomorrow).

Cheers,

Dave.

xfsprogs: build fails to find platform_defs.h

From: Dave Chinner <dchinner@redhat.com>

Commit 2fe8a2 ("libxfs: restructure to match kernel layout") failed
to link plaftorm_defs.h into include/xfs, and so the system header
file is used instead if it exists. If it doesn't exist, the n the
build fails.

Classify platform_defs.h as a header file that is installed in the
xfsprogs package into /usr/include/xfs, and remove the special
one-off install rule that puts it into that directory. This also
ensures that a build will always find platform_defs.h in
./include/xfs rather than relying on the system includes to provide
it, hence also solving the build issue.
