It's certainly true that the way the cross recipes are done at the
moment does suck.  Really, they should be built as primarily native and
the target arch ought to just be encoded into ${PN} somehow, rather than
the current arrangement of pretending that they are target recipes.
(All the runtime bits are, or should be, packaged separately by either
libgcc or gcc-runtime so they will already get the right PACKAGE_ARCH.)

There are some old (and probably rather bit-rotten) patches to do that
in the pb/toolchain-desuck branch of oe-classic.  I'm not sure whether
any of that stuff will apply to modern oe-core but the general principle
ought still to be valid.
