Well, you realize that the ABI is more than just the calling convention?
I.e. your patch basically says ELFOSABI_NONE == ELFOSABI_FREEBSD,
in which case I wonder why the latter exists in the first place. Is there
a proper document somewhere describing everything the latter implies,
so that one can check whether for xSplice purposes such similar
treatment is indeed okay? Until then I'm afraid I'm opposed to this going
in.
