Details:

I am using GNU troff 1.22.4.

The build process for GNU troff allows the use of "V" to enable or disable a
verbose build. The process supports only V=0 or V=1. This is seen in the
Makefile, which contains the definitions of am__v_P_0 and am__v_P_1.

I am trying to build GNU troff for OpenWrt, and the OpenWrt build process,
which surrounds the GNU troff build process in my case, might set V to
something like 99 or another value other than 0 or 1. This breaks the build of
GNU troff.

Could we allow V to be zero or non-zero instead of zero or one?
