We now do all the hard work in a bindistprep subdirectory, and just move
the result to the root directory. This way we can delete anything in
bindistprep/ without worrying about deleting anything important.

Should fix Solaris build failures

We cache the old versions of files generated by configure, so that if
configure touches the file without changing it, we can detect that and
restore the timestamp.

Now that the clean rules don't require libraries/*/ghc.mk, we don't
have to build them on demand.  And having them built on demand
introduced a failure mode (where some libraries have ghc.mk and some
don't).

We still need to sort out the "install-docs" story to get this working
properly.

On Windows, we end up doing something like
    rsync c:/build/ghc-6.10.1-unknown-mingw32.tar.bz2 haskell.org:dist
and it thinks that it is meant to get the file from the host called "c".
Now we just do
    rsync ghc-6.10.1-unknown-mingw32.tar.bz2 haskell.org:dist
so rsync understand what we mean.

It will use TH, so needs to be built with stage2.

This should stop us ending up without HsColour'ed sources on some
platforms.

We also now tell Cabal where to find HsColour, rather than it finding
it itself.

Fixes problems on Solaris, where we need to use gtar instead of tar

We now need to dig the appropriate lines out of packages, rather than
just catting libraries/extra-packages, in order to find out what the
extralibs are.

We don't want to require that users building source dists have alex/happy

e.g. $(bindir)/ghc-6.9.20080911

Hopefully this will fix the SunOS builbot slave.
