New Revision: 169178

URL: http://llvm.org/viewvc/llvm-project?rev=169178&view=rev
Log:
Runtime dynamic linker for MCJIT should support MIPS BigEndian architecture.
This small change adds support for that. It will make all MCJIT tests pass
in make-check on BigEndian platforms.

Patch by Petar Jovanovic.
