[PATCH] D50243: [libunwind][mips] Include gcc_s for linkage

@joerg Would it be okay to commit this?
The LIBUNWIND_HAS_GCC_S_LIB although declared, did not have its value used anywhere unlike LIBUNWIND_HAS_C_LIB and LIBUNWIND_HAS_DL_LIB which had been declared/used similarly.
The added line is only executed if the following block is (`cmake/config-ix.cmake`):

  if (NOT LIBUNWIND_USE_COMPILER_RT)
    check_library_exists(gcc_s __gcc_personality_v0 "" LIBUNWIND_HAS_GCC_S_LIB)
  endif()

in which case compiler-rt is not being used anyway, if that's what you were referring to.
