Hi Arun:
Further verifying the atomic_ops libs installed correctly under
/usr/local/lib:
bash-4.1$ ls -lt /usr/local/lib/*atomic*
-rw-r--r-- 1 root root 5510 Aug 19 09:46 /usr/local/lib/libatomic_ops_gpl.a
-rw-r--r-- 1 root root 3818 Aug 19 09:46 /usr/local/lib/libatomic_ops.a
-rwxr-xr-x 1 root root 948 Aug 19 09:46 /usr/local/lib/libatomic_ops_gpl.la
-rwxr-xr-x 1 root root 936 Aug 19 09:46 /usr/local/lib/libatomic_ops.la
bash-4.1$ ar tv /usr/local/lib/libatomic_ops.a
rw-r--r-- 2147483647/65535 3528 Aug 18 16:46 2014 atomic_ops.o
Thanks,
Allen

Could you try uncommenting this line here:
AC_CHECK_LIB(atomic_ops, main)
http://git.savannah.gnu.org/gitweb/?p=libunwind.git;a=blob_plain;f=acinclude.m4;hb=HEAD
ARM was probably not an interesting platform when the comment was
written. Also not clear why it can't be an inline-able implementation
like other platforms.
