This has been broken since the update to net/asio in november.
Patch imported from upstream git, https://gitlab.gnome.org/World/AbiWord/
as git-patch (which patches m4 files which aren't used) and also
monkeyed into the configure-patch.
The listed PR had an exp-run that failed on this even though
the build failure wasn't related to the exp-run.
