Remove gdb-6.8-bz442765-threaded-exec-test.patch
Following on from the previous commit, this commit remove gdb-6.8-bz442765-threaded-exec-test.patch. Like the previous commit, this patch was a testsuite only patch that extended the test originally added in the previous commit, in order to do some additional threads/exec related testing. The issue exposed by this test (Bug bz442765) was present on Fedora 9, with GDB 6.8-1.fc9. I have setup a Fedora 9 VM and recreated the failure with the test in the patch I'm deleting here. The test does a number of exec's, in each iteration the test binary runs in a different mode. However, the failure is triggered when we have a main thread that spawns a worker thread and then called exec from the main thread. Just like the previous commit, this situation already exists in the upstream test gdb.threads/execl.exp, and, if I copy this upstream test to my Fedora 9 VM, I can reproduce the failure using this upstream test. The test being deleted here does do a number of other permutations of threading and execing, for example it tests calling exec in a non-threaded inferior, but this is also tested upstream with things like gdb.base/foll-exec.exp. In summary, I don't believe there is anything new added by this test that is not already covered with existing upstream tests, as such, I think we should drop this patch.
