These MIPS specific symbols should be global because in general they can have an arbitrary value. By default this value is a fixed offset from .got section.

                                                                            

This patch adds more checks to the mips-gp-local.s test case but marks it as XFAIL because LLD does not allow redefinition of absolute symbols value by a linker script. This should be fixed by https://reviews.llvm.org/D27276.
