+Subject: ARC: handle gcc generated __builtin_trap for older compiler
+
+From: Vineet Gupta <vgupta@synopsys.com>
+
+commit af1be2e21203867cb958aaceed5366e2e24b88e8 upstream.
+
+ARC gcc prior to GNU 2018.03 release didn't have a target specific
+__builtin_trap() implementation, generating default abort() call.
+
+Implement the abort() call - emulating what newer gcc does for the same,
+as suggested by Arnd.
