Bug#1056033: ghc: Please include patch to fix cabal arch detection for sparc64
Source: ghc
Version: 9.4.7-1
Severity: normal
Tags: patch upstream
User: debian-sparc@lists.debian.org
Usertags: sparc64

Hi!
As discussed in private, here is a patch which fixes the arch detection for
sparc64 in cabal. Previously, cabal treated "sparc64" as an alias for 32-bit
sparc which results in the GHC build process not being able to find the built
binaries as these are stored in a $ARCH-$OS subfolder.
The patch has already been pushed upstream, approved and should be merged within
the next hours after some more waiting [1].
The attached patch is a backported version of the patch which applies to GHC 9.4.7.
Thanks,
Adrian
