Dovecot2 can't build for i386 due to dependencies.

[grumpybozo (Bill Cole)]

Dovecot uses Pandoc to build some documentation from its git repo. Pandoc is written in Haskell and depends on the binary-only 'stack' port to load a Haskell environment, but stack is x86_64-only.

The minimal discussion of Pandoc in the Dovecot docs and on the mailing list makes it clear that this is not a required dependency and Pandoc is only used for documents that aren't in a production installation.

To get past this problem, the simplest solution is to remove the build dependency on the pandoc port and add PANDOC=false to configure.env, which is how Dovecot disables Pandoc. I am attaching a patch to this effect.

dovecot2: Remove unnecessary pandoc dependency

Pandoc is only used to build documents that aren't in a production
installation.

This fixes the build for non-x86_64 systems, since Pandoc is written in
Haskell and depends on the stack port which MacPorts only provides as an
x86_64 binary.

Closes: #58890
