Ah, so the last successful build was 3.0.2-2 and the first failure was in 3.0.2-3,
the only difference being the mipsel patch to fix an unaligned access.

However, 3.0.2-2 was built with gcc-10:

> https://buildd.debian.org/status/fetch.php?pkg=ruby3.0&arch=ppc64el&ver=3.0.2-2&stamp=1633362713&raw=0

while 3.0.2-3 was built with gcc-11:

> https://buildd.debian.org/status/fetch.php?pkg=ruby3.0&arch=ppc64el&ver=3.0.2-3&stamp=1634169532&raw=0

So, first we should try building with gcc-10 and see if that makes a difference.
