The TOC scheme may give better locality of reference and thus better
cache performance.  The TOC layout is under control of the compiler,
which generally has better information about data access patterns than
the linker.  Mind you, powerpc gcc doesn't really do anything about
optimising the TOC, but it would be possible.
