Hmm...I don't think so. The MIPS-ABI says that to take advantage of
Quickstart functionality the .dynsym and .rel.dyn section must obey ordering
constraints.

But again  if we forget about Quickstart, under relocations ( Pg 5-13 and
5-14) no such thing is mentioned.
It is mentioned as if it is mandatory for the dynamic relocation section to
be ordered.

Moreover these things mostly matter to the dynamic linker.
