I guess these last two cases could be deleted too?  Doesn't
matter much --- okay anyway.

I think you should still set this, so if the test fails,
the following tests referencing this don't error out reading
a non-existing variable.  Wait, the gdb_test_bi function in
this file, the only user of this variable, isn't itself used
anywhere.  Huh?  This means the variable could be garbage
collected instead, and this gdb_test_multiple below simplified.

Otherwise, it looked fine.  Thanks for all this.
