If you get a failure building .info files ...

Bootstraps will work if you make this in a clean builddir.

They will also work if you delete
(builddir)/gcc/stmp-docobjdir or mkdir (builddir)/gcc/doc.

The reason for this is that the .info and other generated
files are finally being moved out of the source directory
into the build directory -- except for {,pre-}releases.

I'm truly sorry for the inconvience, but it did not seem
sensible to add permenant kludgery to the Makefile for a
one-time potential, yet easily solveable, problem for
developers.
