[PATCH] make sparse headers self-compilable...

Hello,

attached is another fix for SPARSE headers improving their sanity. I am
also attaching a simple test for the dependency tracking of headers. It's
not enough generic and portable and therefore not really useful. Maybe 
someone skilled in writing makefiles might want to include something like
that to the SPARSE Makefile as part of the 'check' target.

Subject: [PATCH] make sparse headers self-compilable...

... and thus possible to include them in arbitrary order and without any
external dependencies.
