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.
