Misc fixes for ld.mcld to build most run-tests.sh

Fixes:
1. Ignore -EL and -EB from MIPS GCC/collect2
2. Translate GNU linker emulation to proper triple
3. Ignore empty archive (eg. In hello-gl2 libstdc++.a is only 8-byte long)
4. Strip llvm-3.x/*/*/bin/* and lib/* unconditionally.  Otherwise ld.mcld
   is more than twice as big

Run:
  ANDROID_SERIAL=none ./run-tests.sh --continue-on-build-fail

Remaining fails (ToDo):
   flto: -plugin -plugin-opt not supported
   [ARM] issue41297-atomic-64bit & static-executable
     Warning: Option gc-sections' is not implemented yet!
     Warning: Option fix-cortex-a8' is not implemented yet!
