I'm afraid I don't have enough experience on that topic. At least my 
cross-platform compiler doesn't seem to do that.

They can't support the .gnu.hash section because MIPS ABI specifies that 
symbols in the dynamic symbol table should be sorted in the same order 
as entries of GOT. There were some experimental patches to sort GOT 
entries accordingly, but they didn't look to be accepted 
(https://sourceware.org/ml/binutils/2007-08/msg00387.html).
