Subject: [PATCH mips-next 2/4] MIPS: vmlinux.lds.S: add ".rel.dyn" to DISCARDS

GCC somehow manages to place some of the symbols from main.c into
.rel.dyn section:

mips-alpine-linux-musl-ld: warning: orphan section `.rel.dyn'
from `init/main.o' being placed in section `.rel.dyn'

I couldn't catch up the exact symbol, but seems like it's harmless
to discard it from the final vmlinux as kernel doesn't use or
support dynamic relocations.

Misc: sort DISCARDS section entries alphabetically.
