bug#51286: [core-updates-frozen] Gawk 5.1.0 test failure (non-deterministic)

Hello,

While rebuilding the core-updates-core-frozen branch locally, I stumbled
upon:

Test suite failed, dumping logs.

To be investigated, but we should probably:

1. report the problem upstream;
2. disable the test.

Thank you,

Seems it had to do with using a minimal variant of Bash instead of the
regular full-fledged Bash.  I've fixed it on the
core-updates-frozen-batched-changes branch.

Closing.
