  Obviously, I can't comment on some mysterious out-of-tree package you have...

  If that package (which I guess will eventually be upstreamed) links with 
anything that is part of the toolchain, that's still fine as long as there's no 
other package (i.e. ATF) links with it (and expects a different target 
architecture).

  However, if the intention is to use the toolchain for a Cortex-M and you need 
any of its libraries, it's probably a lot cleaner to simply have a separate 
arm-gnu-a-toolchain and arm-gnu-rm-toolchain. It's definitely a bit weird to 
have a package "arm-gnu-a-toolchain" that actually uses the -rm one...
