texinfo.tex is in a known location, but only a single copy for GDB and
binutils and a single copy for GCC rather than in each directory needing
it. Is the approach used (for example) in libquadmath/Makefile.am
TEXINFO_TEX = ../gcc/doc/include/texinfo.tex
considered a suitable approach for this case?

I did previously suggest removing the existing support for building and
using these tools in-tree
<http://gcc.gnu.org/ml/gcc-patches/2011-03/msg01674.html>, but there was
pushback on that. I don't know, however, if it actually depends on
anything built into automake.

I'm not aware of a need for that.
