Update MIPS dl-lookup.c from generic version

[Joseph S. Myers]

I've applied this patch to resync the MIPS dl-lookup.c with the generic 
version (one whitespace difference and one substantive change).

We should really work out a way to stop MIPS needing this copy of this 
file (that is, define an appropriate hook architectures can define that 
allows for the MIPS semantics).
