Fair enough, the internal name doesn't matter much. :-)

That's close enough to what others are doing, yeah.

gnueabihf is the best place to aim, yes. Most of what you need is in
place already in the toolchains that people are using (Linaro
toolchain in Ubuntu, upstream-ish gcc in Debian), *except* the change
to move ld.so into /lib/<triplet>/. That's not *critical* yet, but
you'll need to rebuild things to pick up that change once it
happens. You'll be able to cope with it by using compatibility
sym-links, unless you want to support multi-arch...

Cheers,
