Remove support for building sanitizers from Makefile/autoconf build on Linux.

This is a re-application of r229554 restricted to Linux build only.
Apple still uses Makefile/autoconf to build Clang and sanitizers.

 Also ASan runtime needs the following libraries:

-Currently ASan runtime can be built by both make and cmake build systems.
