[U-Boot] [PATCH] MIPS: Introduce --gc-sections for MIPS

[Aaron Williams <Aaron.Williams@caviumnetworks.com>]

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.
