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.

Currently, the cmd/dist runs test cases in misc/cgo/testsantizers only
when memeory sanitizer is supported, but the tsan tests in
misc/cgo/testsanitizers do not require support for -msan option, which
makes tsan tests can not be run on some unsupported -msan option platforms.
Therefore, this patch moves the test constraints from cmd/dist to
msan_test.go, so that the tsan tests in misc/cgo/testsanitizers
can be run on any system where the C compiler supports -fsanitize=thread
option.

This makes it much easier to run individual failing subtests.
Use $(go env CC) instead of always defaulting to clang; this makes it
easier to test with other compilers.
Run C binaries to detect incompatible compiler/kernel pairings instead
of sniffing versions.
