Ah, scratch that, I was overthinking it. The problem is pretty
clear from the error message:
+ ERROR: collation "en-x-icu" for encoding "SQL_ASCII" does not exist
I can reproduce this with vanilla configure options if I'm running
with --with-icu and LANG=C. In short, this regression test does not
work in C locale, and you need to find a way to disable it in that
environment.
