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.
