I just tried it for our Octeon boards and saw a noticeable reduction in size. Our bootloader shrank from 1107840 to 941600 bytes. Size isn't too big of an issue for us, though it's nice to see it shrink to under 1MB again.

All architectures but MIPS are using --gc-sections on final linking. This patch introduces that feature for MIPS to reduce the memory and flash footprint.

Tested with ELDK-4.1 and self-built gcc-4.3.3/binutils-2.19.1 on my boards. I could not test the other boards so I would appreciate it if the maintainers in CC could do a quick test on their boards.

Basically, changes made look good. I'm going to apply after a couple of weeks (or a month) of interval, even without reports from the maintainers. As the patch has been proposed in the last minutes during the merge window, we'll make it in the v2011.06 release, thanks.
