. (which was mostly stolen from elf32-mips.c and slightly adapted).

. generally untested.
|
||
. - Relocation handling for RELA relocs related to GOT support are

. also likely to be wrong.
|

. - Support for MIPS16 is untested.
|
||
. - Combined relocs with RSS_* entries are unsupported.
|
||
. - The whole GOT handling for NewABI is missing, some parts of
|

. the OldABI version is still lying around and should be removed.
