* When my_global_santitize is set and requires ASAN,
link with ASAN library even when local module is not
instrumented with ASAN, unless the local module is
the ASAN library itself.
* Add -Wl,--as-needed to my_ldflags for shared libraries
so that unneeded ASAN library would not become
a dependent of the built .so file.
* Change shared file and executable file link argument order
so that -Wl flags will have effect on linked-in libraries.
* Remove unused ADDRESS_SANITIZER_CONFIG_EXTRA_SHARED_LIBRARIES.
