Safe Haskell validate failure

[David Terei]

Hmmm thats annoying. So the issue is that you need to have the base
package trusted. Originally packages were untrusted by default. I
changed that so that packages are now trusted by default. However that
change to Cabal didn't make it into 7.2.1. So you need to do this for
your bootstrapping 7.2.1 compiler:

$ ghc-pkg trust base

After that it should work fine. I'll look into updating the GHC build
scripts to avoid this.

Cheers,
David
