If we dump the whole of jffs2 into one file and build it with
-funit-at-a-time, it shrinks by about 4KiB on PowerPC, 1.5KiB on i386.

I wonder how much there is to be gained by following that approach
elsewhere.

It'd be a lot nicer if we could tell the compiler that everything is
supposed to be static, instead of having to play with the source code.
