Re: [patch][objc] Do not call assemble_external

Hi Steven,

Ah, that's the bit I'd yet to figure out ...

Bootstrapped&tested on powerpc64-unknown-linux-gnu. OK for trunk?

Ciao!

objc/
* objc-act (objc_build_ivar_assignment): Do not call assemble_external.
(objc_build_global_assignment): Likewise.
(objc_build_strong_cast_assignment): Likewise.
* objc-next-runtime-abi-01.c: Cleanup commented-out assemble_external.
* objc-next-runtime-abi-02.c: Likewise.
* objc-gnu-runtime-abi-01.c: Likewise.
<cleanup_objc_assemble_external.diff>

... this would allow us to close PR17982?

... and make progress on PR24777? (I'm not sure where exactly we need to go with this one - we have different sets of calls depending on the runtime)
