Is "make bootstrap" known to be broken on mainline?

A couple of days ago, I tried to do a "make bootstrap" on an up-to-date 
copy of mainline, on a freshly-installed Debian Linux machine.  After 
several hours of anticipation, I got the following error:

I understand from conversation on IRC that this is a known problem, 
related to one of the patches checked in recently that's the subject of 
some discussion.

Is this correct?

If so, is there a reasonable workaround for this that will enable me to 
bootstrap-test the Fortran changes that I'm currently working on, so 
that this isn't holding up everything I'm doing?  Ideally, a workaround 
that will not require me to track the relevant conversations here to 
find out when to back out the workaround, but I suppose I can't be too
