Naming targets. ppc-405-linux?

One good source of target tuples that are in use for gnu tools
seems to be the Debian 'archtable' file:
http://cvs.debian.org/dpkg/archtable?rev=1.21.2.4&cvsroot=dpkg
This handles a lot of chip variations, e.g.
i386-linux-gnu
i486-linux-gnu
i586-linux-gnu
i686-linux-gnu
ppc
powerpc
powerpcle
powerpc64
sh3-linux-gnu
sh4-linux-gnu
sh3eb-linux-gnu
sh4eb-linux-gnu
Yet there are more variations out in the field, for instance,
the ppc405, which can't run programs compiled for normal powerpc
(it has quirks that need workarounds). And you can't configure
for ppc405-linux; binutils barfs on that.
For those chips which don't have standard targets, and which need
their own toolchains, it looks like
the way to go is to jam the specific chip type into the middle
(vendor) field of the target name, e.g.
ppc-405-linux
for an embedded Linux system with an IBM PPC405 chip.
Does that sound about right?
