Here is the patch, I had posted it to gcc@gcc.gnu.org for comments, but 
since there were none...

Jar is not used yet, but it could as well be.  Surely it is easier to 
add it with this scheme in place.

Regtested on a native i686-pc-linux-gnu configuration, and on a 
pseudo-Canadian with build=i686-pc-linux-gnu, host=i386-pc-linux-gnu, 
target=i386-pc-openbsd.  In both cases the in-tree makeinfo was always 
used.  Ok for mainline and src?
