IMO, if GDB for a certain target doesn't handle "return" and "finish"
correctly, the return value can be some random results.  Why do we match
"\\{10, 20, 48, 72\\}" here?  I presume that because "10, 20, 48, 72"
was returned in the previous test.  Do *all* targets don't correctly handle
"return" and "finish" return "\\{10, 20, 48, 72\\}"?  In other words, if
we know it is broken already, why do still match the output?  We can
kfail it according to the target triplet.
