I tried to bisect things down a bit, but as some later fixes are
required (at one point, date was returning the start epoch and never
increasing), this hasn't worked too well. But I'm guessing since I
see: "CROSS_COMPILE_COMPAT not defined or empty, the compat vDSO will
not be built", and the system is half working, I'm guessing this is an
issue with just the 32bit code failing.  While I can try to sort out
the proper CROSS_COMPILE_COMPAT in my build environment, I assume
userland shouldn't be crashing if that value isn't set.

Any chance this issue has already been raised?

First I've seen of it, although Vincenzo is likely to know better than me.
In the meantime, please can you share your .config?

I think the key is: CROSS_COMPILE_COMPAT not defined or empty. And then run
32bit userspace.

Thanks,
