Looks like it's gcc that crashes not ld. If you're sure it's not a 
hardware problem this may be a gcc bug. Sometimes big compile jobs can 
break if a machine is not stable but if it always fails at the same place 
and does not fail when compiling something else like a Linux kernel then 
it's more likely to be an actual bug. That function has some crazy use of 
macros so maybe it's exposing some bug in gcc. You could restrict what 
targets you build with --target-list configure option of QEMU if you don't 
actually need mips (compiling will be faster if you only build the targets 
you need) or you can try with clang if available in your distro to check 
if that works better. If this can be consistently reproduced you could try 
reporting it to gcc as the error message suggests. Probably not much QEMU 
can do about it.
