Okay.  In that case I'm taking myself out of the loop on this issue; I
think Richard might need to work up some documentation for how
Yocto/OpenEmbedded attempts builds of projects using GNU Automake.

If "make clean" doesn't trash the dependency information that "make all"
creates,[1] then "make libgroff.a" or "make doc/groff-man-pages.pdf"
might still be a useful technique for smoking out missing prerequisite
declarations in groff's *.am files.

Regards,
Branden

[1] A quick experiment suggests that it doesn't.

    $ make all
    ...
    $ make clean
    ...
    $ find -name '*.Po' | head
    ./src/roff/groff/.deps/pipeline.Po
    ./src/roff/groff/.deps/groff.Po
    ./src/roff/troff/.deps/div.Po
    ./src/roff/troff/.deps/majorminor.Po
    ./src/roff/troff/.deps/mtsm.Po
    ./src/roff/troff/.deps/number.Po
    ./src/roff/troff/.deps/dictionary.Po
    ./src/roff/troff/.deps/input.Po
    ./src/roff/troff/.deps/env.Po
    ./src/roff/troff/.deps/reg.Po
