Subject: Refactor package installation
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=e542d75c0a4b529aeafc0fc51038d670a8adc74c

Refactor package installation
There is now less makefile code duplication.
Also, stage2 packages are registered after GHC, which is important as
they might depend on the ghc package (as dph now does).
