The follow mips asm fragment when assembled and link -shared the following error messages from ld:

Obviously that change should not caused anything to change but it did. It seems that when the reloc is
emitted, the $LC4 + 5 should have been changed to .rodata.str1.8 + offset($LC4) + 5. This bug exists
in 2.16 and in 2.19 and on HEAD.
