A top level "make build", as used e.g. by osstest, wants to build all "all" targets in enabled tools subdirectories, which by default also includes the emulator test harness. The use of, in particular, AVX512 insns in, again in particular, test_x86_emulator.c causes this build to fail though when the compiler is not new enough. Take a big hammer and suppress the default harness build altogether when any of the extensions used is not supported by the specified (or defaulted to) compiler. Leave the "run" target alone though: While some of the test code blobs may fail to build with older compilers, as long as the main executable can be built some limited testing can still be done.
