I don't think it necessarily is a bug because the macros is not
except for ABI_AIX.
I want to avoid adding new definitions or expanding definitions to
cover cases that don't exist because someone later will interpret that as
self-documenting code: "This was done on purpose." Or later will enable
some 32/64-bit thunk mode that breaks because of this. Where possible, I
would like to avoid making things selectable when the other case never
Please keep RS6000_CALL_GLUE uniformly defined to "nop". If this
breaks something, we have a worse problem.
