Include compiler version in ABI hash

[nomeata]

Hi,

as outlined in the discussion at  http://lists.debian.org/1310417783.21421.22.camel@kirk, it would be beneficial if the ABI hash of packages would change if compiled by a different version of the compiler – after all, the interface files of such a package would not be usable any more.

Debian uses the abi hashes to detect what needs to be rebuilt, hence we have an interest in this.

The attached patch has been applied to ghc in Debian unstable already, and I’d greatly appreciate if it or something with the same effect would enter the main line.
