Hmm, OK - in which case would it be acceptable to say that in order to
obtain GDB support an SH toolchain should be configured as "sh-elf"
and not "sh3-elf" even if the intended default processor is the SH3 ?
ie that configurations such as "sh3-elf" are becoming obsolete and
will one day be removed ?
