Linus Torvalds feaebd0e0a Make 'cc-option' work correctly for the -Wno-xyzzy pattern 
[ Upstream commit 550ccb178d ]

This is the follow-up to commit a79be02bba ("Fix mis-uses of
'cc-option' for warning disablement") where I mentioned that the best
fix would be to just make 'cc-option' a bit smarter, and work for all
compiler options, including the '-Wno-xyzzy' pattern that it used to
accept unknown options for.

It turns out that fixing cc-option is pretty straightforward: just
rewrite any '-Wno-xyzzy' option pattern to use '-Wxyzzy' instead for
testing.

That makes the whole artificial distinction between 'cc-option' and
'cc-disable-warning' go away, and we can happily forget about the odd
build rule that you have to treat compiler options that disable warnings
specially.

The 'cc-disable-warning' helper remains as a backwards compatibility
syntax for now, but is implemented in terms of the new and improved
cc-option.
