We don't yet handle the thread-local-data relocations (TP* and DTP*)
in the linker yet, but here they are for objdump purposes.
r~
Update relocations per August psABI docs.
* ia64.h (R_IA64_SEGBASE): Remove.
(R_IA64_LTV*): Renumber to 0x74 to 0x77.
(R_IA64_EPLTMSB, R_IA64_EPLTLSB): Remove.
(R_IA64_TPREL14, R_IA64_TPREL64I): New.
(R_IA64_DTPMOD*): New.
(R_IA64_DTPREL*): New.
