Revert r240302 ("Bring r240130 back."). This causes errors like: ld: error: blah.o: requires dynamic R_X86_64_PC32 reloc against '' which may overflow at runtime; recompile with -fPIC blah.cc:function f(): error: undefined reference to '' blah.o:g(): error: undefined reference to '' I have not yet come up with an appropriate reproduction. llvm-svn: 240394

[SPARC] Repair GOT references to internal symbols. They had been getting emitted as a section + offset reference, which is bogus since the value needs to be the offset within the GOT, not the actual address of the symbol's object.
