libsanitizer: Tie the hwasan library into our build system

This patch tries to tie libhwasan into the GCC build system in the same way
that the other sanitizer runtime libraries are handled.

libsanitizer/ChangeLog:

	* Makefile.am:  Build libhwasan.
	* Makefile.in:  Build libhwasan.
	* asan/Makefile.in:  Build libhwasan.
	* configure:  Build libhwasan.
	* configure.ac:  Build libhwasan.
	* hwasan/Makefile.am: New file.
	* hwasan/Makefile.in: New file.
	* hwasan/libtool-version: New file.
	* interception/Makefile.in: Build libhwasan.
	* libbacktrace/Makefile.in: Build libhwasan.
	* libsanitizer.spec.in: Build libhwasan.
	* lsan/Makefile.in: Build libhwasan.
	* sanitizer_common/Makefile.in: Build libhwasan.
	* tsan/Makefile.in: Build libhwasan.
	* ubsan/Makefile.in: Build libhwasan.
