With in-tree GCC 12.4, kernel crashes just same as 12.3 :(

Even a single character is output to console. I tried to
drop some features from kernel config to reduce size
significantly, but it does not help. On the other hand,
same kernel works just fine if compiled by GCC 10.5.

I've noticed that GCC/sh is relatively active these days;
some people are developing their own SDK for Dreamcast.
These updates made our configuration stale?

Thanks,
