your thumb-plt tests for Arm32

[Jan Beulich]

Tamar,

while building 2.35 for various cross targets, I've run into failures
with these two tests. After some looking around I come to the
conclusion that they're likely too strict in their expectations, in
not allowing things like GNU_HASH that may get enabled automatically
for certain configurations. I haven't, however, figured exactly what
parts of the expectations could be relaxed without breaking their
purpose. Could you take a look please?
