Fix test case link failure on PowerPC systems with Altivec

Upstream-Status:backport

On systems where the system compiler supports Altivec by default,
the libunwind Makefile will attempt to build an extra test case
ppc64-test-altivec.  Unfortunately, the link step will fail since
the Makefile does not actually link against the libunwind library.

Fixed by adding the appropriate LDADD macro.
