The problem is that with the current supported_archs setting in stack, you hit
this architecture mismatch error when trying to install pandoc on the M1:
Cannot install pandoc for the arch 'arm64' because
It’s dependency stack is only installed for the arch 'x86_64'
and does not have a universal variant.
Unable to execute port: architecture mismatch
Then the error is correct; you can't build an arm64 pandoc with an
x86_64 stack. The pandoc port is just following the global build_arch
setting since it does not set supported_archs and the default is to
assume that all archs are supported. Since it can only actually build
for x86_64, pandoc should set supported_archs accordingly.
