ECMEnableSanitizers: avoid linking runtime for Clangv5.21.0-rc2v5.21.0-rc1v5.21.0
Clang automatically adds its runtime library (librt) when given the
-fsanitize options. Do not force the GCC runtime libraries (asan, tsan,
lsan), this results in "Your application is linked against incompatible
ASan runtimes." errors when using the library in an executable built
using Clang.
