Ok?
Per previous discussion. This modifies ecoffswap.h for 32 and 64 bit
MIPS targets so debug information is sign extended when being stored in
a bfd_vma.

* ecoffswap.h (ecoff_get_off, ecoff_put_off): Add ECOFF_SIGNED_32
and ECOF_SIGNED_64 to list ways to extract an offset.
* elf64-mips.c (ECOFF_SIGNED_64): Define instead of ECOFF_64.
* elf32-mips.c (ECOFF_SIGNED_32): Define instead of ECOFF_32.
