It is technically possible to use an arm-linux toolchain where one would
normally use an arm-none toolchain. But there are subtle differences
between the two at the library interface level, I have found that the
*-linux toolchain tends to depend on library functions that bare-metal
systems often don't have.
It's also a matter of clarity for developers. "Why would I want a
*-linux toolchain, I'm not building for a Linux target".

Yes, and they are all fabulous. Particularly if you are trying to
manage Debian in cross-platform environments. But they aren't
particularly optimal for what the OP is trying to accomplish, which is
to produce a toolchain that can be used as a starting point for a
bare-metal application.

I like the idea of having cross toolchain packages that are "sociable"
with the Debian system. However, that really isn't a consideration for
a binutils-arm-none toolchain: its work products are by definition not
compatible with Debian--- or even Linux. So the concerns for this
situation come down to making sure that his packaging approach is
consistent with other Debian packages for non-Debian toolchains, AFAICT.
