Hi!

There is a new project called J-Core that is working on reimplementing the old
SuperH architecture as an open source architecture. They are currently supporting
the SH-2 CPU (called J-2) and are working to release the more powerful J-3
CPU which is based on the SH-3 design.

In order to bootstrap Debian on "sh3", we need to add it as a compilation target
to guile. This is done by the attached patch which adds the case for "sh3" for
cpu-endianness and triplet-pointer-size in module/system/base/target.scm.

Would be great to have this applied to be able to support Debian on an actual
open source CPU.

Thanks,
Adrian
