boehm-gc support for s390 architecture

[Boehm, Hans]

I've attached a diff between the 3.1 version of cordprnt.c and my current
development version.  This was also based on the Debian code, but it seems
slightly safer to me.  But I haven't done a lot of portability testing.  I'm
open to better ways of doing this.

Note that AFAIK, nothing in boehm-gc/cord is actually used by gcj.
