Hi Meher,
The change that you applied to your lttng-ust configure.ac should look
like this:
diff --git a/configure.ac b/configure.ac
index ea73243..efb16d4 100644
--- a/configure.ac
+++ b/configure.ac

*) AC_MSG_ERROR([unable to detect library format (unsupported
architecture ($host_cpu)?)]) ;;
Make sure after making this change that you run the autoreconf command
like this:
autoreconf -i -v
And then rerun ./configure with your platform specific flags.
The configure test should now pass without problem :).
Thanks,
Christian
