I am working on it. I need to get past some new silly dependency that
makes little sense given that the bootstrap fails in stage 3 of all
places :

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82686

So I should ( in theory ) be able to build the gc code in place and in 
the tree in the same manner as gmp, mpfr, mpc and isl.  So I am working
on that but it just isn't working.

In any case I'll get the sources from http://www.hboehm.info/gc/ and 
keep hacking at this on ppc64.
