+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.
