This commit removes that bitrotting part of Prelude.hs. This reduces the
CPP clutter to the point of not requiring any CPP processing altogether
anymore. The same clanup was performed in the haskell2010 package
recently.

Doesn't seem to have any effect with GHC HEAD.

We now keep the HEAD version numbers as values which would be suitable
for immediate release.

It was linking to System.Random, but that's not in haskell98.

The behaviour of gcd was changed to "gcd 0 0 = 0", here we must keep
the haskell98 behaviour and raise an error.

Prelude is necessary now base's Prelude is deprecating/removing catch.

As a result, the package is now not exposed by default, to avoid
ambiguous module problems.

And we therefore can't use haskell98 and base together, so haskell98
also needs a copy of Numeric.
