If Graphite can be disabled then the bootstrapping issue goes away as you
can in a first step build current GCC with C++ enabled and do a second stage
with Graphite enabled.

I agree.  At least this is the place for requesting Host testing on
non-Linux hosts.
Note that Fedora has packages for the PPL, likewise has Debian.  I am in
the progress of building ones for SUSE.
