Subject: [PATCH 072/158] [Xtensa] Add a no-op -mlongcalls option for better

 compatibility

Many projects targeting Xtensa architecture use GCC-specific
-mlongcalls option. The current behavior of LLVM for Xtensa is
equivalent to this option being set, so accept this option without
changing the behavior.
