This is an attempt to avoid a problem with Racket BC on ppc64 reported
in <https://issues.guix.gnu.org/57050#19> that was exposed by attempting

the workaround: <https://racket.discourse.group/t/950/30>.

On systems for which Racket's variant of Chez Scheme cannot generate
native code, it can use a 'pbarch' machine type: a variant of the
``portable bytecode'' backend specialized to word size and endianness.
This allows Racket CS to replace Racket BC on those systems while
maintaining comparable performance. (Racket BC lacks JIT support for
those systems anyway.) It also lets us provide a Chez Scheme package on
all systems Guix supports.
This patch adds 'pbarch' support to both 'chez-scheme-for-racket' and
'racket-vm-cs', but it does not change the Racket VM implementation used
for the 'racket' and 'racket-minimal' packages.
* gnu/packages/chez.scm (nix-system->pbarch-machine-type): New variable.

Cross-compilation works for 'racket-vm-cgc', 'racket-vm-bc', and

easier once we can build the package 'raco-cross'.
