Follow-up Comment #2, bug #59186 (project groff): The true culprit appears to be the commit that relocated mdoc within the build tree.
commit de1e4091311d74ab2af19aa0d376c5d228a14280 Author: G. Branden Robinson <g.branden.robin...@gmail.com> Date: Tue Aug 25 17:52:55 2020 +1000 mdoc: Relocate within build tree. The (modern) mdoc macro package has not been usable within the build tree, unlike the others. This makes it more troublesome to test changes, and frustrates deploying our test infrastructure against it. Re-arrange the build tree to resemble an installation tree closely enough for the macro package to load. renamed: doc-common-u -> mdoc/doc-common-u renamed: doc-ditroff-u -> mdoc/doc-ditroff-u renamed: doc-nroff-u -> mdoc/doc-nroff-u renamed: doc-syms-u -> mdoc/doc-syms-u * tmac/tmac.am (TMACMDOCFILES): Look for files in tmac/mdoc. ($(TMACMDOCFILES)): Create tmac/mdoc in build tree.
