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.

ARM64's R19-R29 and F8-F15 are callee saved registers, which
should be saved in the beginning of sigtramp, and restored at
the end.

With latest gcc (7.3.0), misc/cgo/testsanitizer test will fail with reporting sigmentation
fault when running tsan test. On arm64, tsan is not supported currently and only msan test
can be run. So skip tsan test on arm64.
What needs to be pointed out is that msan test can be really run when setting clang
as c/c++ complier.

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.
