Comment:
I think the problem here is that `stack` downloads a version of `ghc` that is only for `x86_64`. The template as is should either set `archs="x86_64"` or set `broken` when `"$XBPS_TARGET_MACHINE" != "x86_64"`. (The `archs` variable is really meant to indicate an upstream support limitation, not necessarily a consequence of XBPS packaging details or version incompatibilities.) It's not clear to me what option would be preferable here.
