update on cabal-rpm-0.8 and ghc-7.6.3

[Jens Petersen]

More details on the failures:

>   ForSyde

Missing module Language.Haskell.TH.Syntax.Internals

>   happstack-server

UTCTime vs ClockTime mismatch

>   ghc-hledger-lib (hledger)

hledger-lib-0.19.3 built but hledger-0.19.3 still needs shakespeare-text!

>   cabal-dev

Fixed by patching Cabal and built cab too.

>   ltk (leksah-server,leksah)

I will try a snapshot from git with ghc-7.6 fixes.

> also git-annex needs to be bumped but that needs some additional new deps.

At least SafeSemaphore is needed (also uuid for current releases)
