Subject: [bug#42014] [PATCH] WIP: gnu: Re-bootstrap Haskell with GHC 8.2.2 binaries.
Date: Sat, 27 Jun 2020 22:09:48 +0000

Hi Ricardo,

I actually had the same thought, and asked about it on IRC with no response. So I just did the simplest thing I could to get started. Once we have a working compiler on ARM, it should be pretty easy to restore the old x86 bootstrap path.

In particular, the complexities of having the GHC 8.4 package bootstrapped from upstream binaries on some architectures vs a previous package on others, just seemed like an unnecessary distraction until we can work through the build problems on ARM.
