Hi Zoltan can be the gcc, in past on ppc we face the same kind of issue.
 i will ask some other guys in the debian ppc ML if can try to build qemu and see if they have the same issue. in positive case we will report to the mantainer.

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.
