This appears to be an incompatibility in the script between running with
/bin/sh (ksh on the platform) and bash. When we use make
SHELL=/usr/coreutils/bin/bash (where our bash is located), this test passes.
We will use this construct going forward, assuming we don't encounter
something weird. So far, only t0301 and t1091 are failing. These are new
failures. I will investigate and report on these separately.
