Lynn Boger d4ff25ac69 misc/cgo/testsanitizers: determine compiler version for tsan tests on ppc64le
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.

Updates #54645
