I see.

It won't quite work.  The manual/dir-add.{texi,info} targets and the
manual/% pattern rule right below the INSTALL target were intended to cover
such things.  But those are now bit rot from the time we had things
changing in source directories.  So those should be replaced by:

$(common-objpfx)manual/%: FORCE

with the same commands, or something like that.
