Actually, upon closer inspection, texi2html has nothing to do with this. The 
host needs to have pnmcut, pnmcrop, pnmtopng, psselect, pnmtops and gs 
installed or neither the HTML nor PDF backends for groff will be enabled.

This leaves us with two alternatives:

1) Make groff depend on ghostscript, and that would at least enable the PDF 
backend, but for HTML it still leaves netpbm (for pnm*) and psutils (for 
psselect), neither of which we have in OE-Core.

2) Alternatively I can add --without-gs to the groff configure options which 
will always disable both backends.

Cheers,
Paul
