kbuild: Cache a few more calls to the compiler
These are a few stragglers that I left out of the original patch to cache calls to the C compiler ("kbuild: Add a cache for generated variables") because they bleed out into the main Makefile and thus uglify things a little bit. The idea is the same here, though.
