Why do you need such complex detection? Also in nss ebuild I see
different detection:

It looks like good idea to unify them.

Or you could use, you know, $(tc-arch) from toolchain-funcs.eclass?

Is it possibly similar to the scenario from
<http://bugs.gentoo.org/show_bug.cgi?id=296917>, i.e. multilib portage
and other non-standard configurations? If so, it may also be useful to
re-use the detection logic in www-client/chromium and dev-lang/v8.
