Correct the generation of OR1K pc-relative relocations.
gas PR ld/18759 * config/tc-or1k.c (tc_gen_reloc): Correct computation of PC relative relocs. * config/tc-or1k.h (GAS_CGEN_PRCEL_R_TYPE): Delete. bfd * elf32-or1k.c (R_OR1K_32_PCREL): Set pcrel_offset to TRUE. (R_OR1K_16_PCREL): Likewise. (R_OR1K_8_PCREL): Likewise. ld/tests * ld-elf/eh-frame-hdr: Expect to pass on the or1k-linux target.
