TS		 30/* TODO: Many things are unsupported, even if there is some code for it
31 . (which was mostly stolen from elf32-mips.c and slightly adapted).
32 .
33 . - Relocation handling for REL relocs is wrong in many cases and
34 . generally untested.
35 . - Relocation handling for RELA relocs related to GOT support are
36 . also likely to be wrong.
37 . - Support for MIPS16 is only partially implemented.
38 . - Embedded PIC is only partially implemented (is it needed?).
39 . - Combined relocs with RSS_* entries are unsupported.
40 . - The whole GOT handling for NewABI is missing, some parts of
c6e90b02 41 . the OldABI version is still lying around and should be removed.
