Revert "bfd: allow negative offsets to _GLOBAL_OFFSET_TABLE_ in elf64 SPARC"
This reverts commit b19753ce31da347605dfa903c6fd2158e2444f0d. As it turns out, GCC (and the assembler) needs additional work in order to support negative GOT offsets in 64-bit sparc. This is breaking TLS Local Dynamic in position-independent code.
