I've now pushed the simplified fix (without changing the SET_ERRNO()
macro, enough last minute breaking changes for now) in branch
20230815-for-6.6-2.

The tests pass and riscv/loongarch are even very slightly smaller than
before (~8 bytes) but again that doesn't count as it depends on how the
compiler decides to arrange if/else branches.

I'll let Shuah know about these late fixes.

Regards,
Willy
