  When GCC is configured with --enable-target-optspace the compiler generates
a memcpy call in the Symbolizer constructor in sanitizer_symbolizer.cpp
when compiling for SPARC V8. Add HAVE_AS_SYM_ASSIGN to replace it with a
call to __sanitizer_internal_memcpy.

libsanitizer/ChangeLog:

	* sanitizer_common/Makefile.am (DEFS): Add @AS_SYM_ASSIGN_DEFS@.
	* sanitizer_common/Makefile.in: Regenerate.

We have only been granted write approval for the SPARC port. Is it
ok to push this anyway or could you help us with it?

I don't think anyone has write access only to a part of the git repository.
So, if you are Write After Approval (which seems you are according to
MAINTAINERS), you should be able to commit any patch approved by
maintainers or reviewers.
