kbuild: disable sparse warnings about unknown attributes

Currently, sparse issues warnings on code using an attribute
it doesn't know about.

One of the problem with this is that these warnings have no
value for the developer, it's just noise for him. At best these
warnings tell something about some deficiencies of sparse itself
but not about a potential problem with code analyzed.

A second problem with this is that sparse release are, alas,
less frequent than new attributes are added to GCC.

So, avoid the noise by asking sparse to not warn about
attributes it doesn't know about.
