- Subject: Fix unused-variable warnings from MIPS RESOLVE_GOTSYM macro
Building for MIPS produces warnings about the variable "version" in
the RESOLVE_GOTSYM macro being unused when building dl-conflict.c,
where RESOLVE_MAP is defined with a definition that doesn't use that
macro argument. I've applied this patch to fix these warnings by
using __attribute__ ((unused)) on that variable.

* sysdeps/mips/dl-machine.h (RESOLVE_GOTSYM): Declare VERSION
variable with __attribute__ ((unused)).
