2.08 little bug

[Justin Cormack]

Just a minor thing in 2.08, install copies the driver to bin/ghc and sets
a symlink from ghc-2.08 to ghc rather than the other way round so it overwrites
the old copy...

  94 -rwxr-xr-x   1 jpc1        95903 Oct  9 17:56 ghc
   1 lrwxrwxrwx   1 jpc1            3 Oct  2 17:01 ghc-2.07 -> ghc
   1 lrwxrwxrwx   1 jpc1            3 Oct  9 17:56 ghc-2.08 -> ghc

totally painless install (from sparc solaris binary) otherwise.
