Some tests in misc/cgo/testsanitizers had been disabled on ppc64le until recently, due to an intermittent error in the tsan tests, with the goal of trying to understand the failure. After further investigation, I found that the code for tsan within gcc does not work consistently when ASLR is enabled on ppc64le. A fix for that problem was integrated in gcc 9. This adds a check to testsanitizers to determine the gcc compiler version on ppc64le and skip the test if the version is too old. A similar check is needed for asan too.
