[tex-live] pool files integrated into all binaries

[Karl Berry]

Thanks to Akira, the pool files for tex, mf, and etex (not that we
install the separate etex binary any more) along with aleph and omega,
are now compiled into the binaries, using the technique that Taco
developed some time ago for mpost, luatex, pdftex.

The result should be no more painful "tangle me again" messages.  We can
hope, anyway.
