I meant that groff is never called by FreeType's build system, as the
man page is hand-crafted.

Lintian issues the warning when checking for man-page issues using
groff (via man). This particular warning has only appeared since the
recent groff 1.23.0 upload.
The Lintian tag is 'groff-message'. The tag description helpfully
provides the exact command used during the check:
LC_ALL=C.UTF-8 MANROFFSEQ='' MANWIDTH=80 \
man --warnings -E UTF-8 -l -Tutf8 -Z <file> >/dev/null
The man page in question -- ftlint.1 -- is in the freetype2-demos
package [1], or you can get an online copy from [2].
[1] /usr/share/man/man1/ftlint.1.gz
