The memory barriers where introduced with commit "test-timeout: fix build errors with -std=gnu++20" presumably in order to prevent GCC optimization from removing the empty for loops the test is using because using a volatile index variable was no longer an option. However, the memory barriers seem to have a negative effect on the measurements performed with the affected loops. The commit caused the timeout test to fail at least on imx53_qsb. This commit fixes the issue by using a simple empty for loop without volatiles or memory barriers but protected inside a function that is compiled with optimization disabled. Ref #4959
