glibc, package.bbclass: generate old-style binary locales at build time using qemu. based on a patch originally written by Phil Blundell. fixes hh.org Bug #1385 (localedef OOM issue).

  - running localedef (in qemu...) for every locale takes a while. set
    BINARY_LOCALE_ARCHES = "" to avoid the new behaviour.
