To append info to a GNATS entry, make sure you CC:
gcc-gnats@gcc.gnu.org, and make sure that the Subject:
field of your e-mail contains the GNATS ID for the Problem Report,
ie.

"Subject:  Re: Re: bootstrap/3641: can not bootstrap on....."

If you can figure out a good place to put this in documentation,
I'll write a patch for it.

There is a patch very similar to what you are talking about,
but meant to address the problem of bootstrapping on
older versions of glibc.

I submitted this patch, to detect the existence of ucontext.h
in the configure script:

http://gcc.gnu.org/ml/gcc-patches/2001-10/msg01543.html

The next part of the patch, which I have not tested yet is
here:
http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view&pr=4068&database=gcc

Does that patch look like it would work for your problem?
