From: Paolo 'Blaisorblade' Giarrusso <[email protected]>
Make sparse checker work for userspace files - it normally gets -nostdinc
separately, so avoid having it for userspace files. Also, add -D$(SUBARCH) for
multiarch hosts (i.e. AMD64 with compatibility headers).
It works, the only problem is a bit of bogus warnings for system headers, but
they're not too many.
