valgrind: import Debian link_tool patch for MIPS

Without this patch, valgrind 3.10.1 fails to run on MIPS:

 | root@bcm97425vms:~# valgrind /bin/ls
 | valgrind: mmap(0x400000, 700416) failed in UME with error 22 (Invalid argument).
 | valgrind: this can be caused by executables with very large text, data or bss segments.
