Add -Wmissing-prototypes to STRICT clang builds.

Browse Source 
Ben added -Wmissing-declarations in commit 3a3e491a8bc624e for gcc
builds, and observed that clang's option of the same name doesn't do
the same job. But clang does _have_ an option to do the same job: it's
just spelled differently. Added -Wmissing-prototypes in clang builds,
so that those will check the same thing.
