disallow direct inclussion of <linux/*.h>

[Robert Millan]

Hi folks!

I think we should disallow direct inclusion of <linux/*.h> in Glibc, any
comments?

Sort of like:

#ifndef _USE_LINUX
# error "Never include <linux/*.h> directly; use standard headers instead."
#endif

If you (specialy Roland) like the idea, I can send it to the Glibc lists. (and
write a patch).
