-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.

-Date: Fri, 27 Jun 2014 08:40:33 +0200
-Subject: [PATCH] Link libunwind to libgcc_s rather than libgcc
-
-For some architectures, -lgcc and -lgcc_s are not equivalent. On ARM for
-example, libgcc_s.so.1 contains some symbols needed by libunwind which
-are not present in libgcc.
-
-This causes the following link error when building the X.Org X server
-with libunwind support:
-
-	  CCLD     Xorg
-	/usr/lib/libunwind.so: undefined reference to `__aeabi_unwind_cpp_pr0'
-	/usr/lib/libunwind.so: undefined reference to `__aeabi_unwind_cpp_pr1'
-
-Linking against libgcc_s explicitly solves this problem.
