[oe] gcc-cross-4.3.3 build failure - PPC/Sequoia

[Jeremy Williams]

Looks like a recent commit applies a patch to libobjc in gcc-4.3.3 that causes
the build of gcc-cross-4.3.3 on PPC to fail (and I'm assuming other non-ARM
machines as well).

gcc 4.3.4: add objective-c patch for eabi and add a package for libobjc
27622153e629cdff24e0f528b4802019d7f87f81 

The issue lies in the failure to remove the old "#define __objc_exception_class"
macro in the (#else (non ARM_EABI_UNWINDER) case.

Koen, since this one is yours can you revert and apply a fix? Might want to
update the headline too, this patch is applied to gcc 4.3.3 not 4.3.4.

Thanks!
