I can't exactly guess, so when the arm mac builds a haskell port using this addition, what do they look like?

Does macports think it installed an arm port (and registered it as such)?

But is it really arch x86_64?

This is stated both in the code and above:

stack builds x86_64 binaries on both arm64 and x86_64 architectures

The binaries it builds run on both arm64 and x86_64 architectures.

If so, no bueno.

Yes, bueno. x86_64 binaries run on arm; therefore, haskell-built ports supports both arm64 and x86_64. Otherwise there’s a bug in MacPorts identified in the trac ticket.

sell it to Ryan, then. He turned this idea down 10 times already :)

[essandess]

I do not know what you are referring to.

The only fixes I'm aware for the haskell-related arm/intel install issues is to:

1. Add the supported_archs for both Arm and Intel because both work.
2. Remove the supported_archs directive completely.
3. Fix whatever MacPorts issue causes https://trac.macports.org/ticket/63944

The first is the obvious, simplest and I believe correct approach.

@ryandesign May we please get some of your cycles on this PR?

As it stands on M1, haskell_stack port builds fail with an architecture mismatch error, e.g.

sudo port -pNc destroot adblock2privoxy
Error: Cannot install adblock2privoxy for the arch 'x86_64' because
Error: its dependency stack is only installed for the arch 'arm64'
Error: and does not have a universal variant.
Error: Unable to execute port: architecture mismatch

I'm happy to kick this upstairs to a general MacPorts bug if necessary, but something is definitely broken in the logic of building with stack on M1, and this PR fixes it.
