These changes need to be made RDC or x86 specific. RISC architectures
typically need completely different LZMA options compared to x86,
because of patterns in fixed vs variable instruction length code.
I just compared your parameters with the default ones on a mips kernel
binary, and here's the difference:

default: 923668 bytes
yours:   939529 bytes
