The current MAX_SMP check launches QEMU for every value of the SMP parameter to check if the SMP parameter based on the native is higher than the QEMU maximum supported configuration. On something like a TX2, which has 224 threads, this takes a very long time where the test script just sits there with no output. Reduce the wait time by taking the log2 of MAX_SMP in each iteration of the loop instead.
