im try to build last relesase on a PowerMac G5 quad on debian sid PPC64 but ld 
exit with an error:

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.

 mv64361: Remove extra break from a switch case (2021-07-13 10:12:17 +1000)

ppc patch queue 2021-07-13

I thought I'd sent the last PR before the 6.1 soft freeze, but
unfortunately I need one more.  This last minute one puts in a SLOF
update, along with a couple of bugfixes.

Alexey Kardashevskiy (1):
     pseries: Update SLOF firmware image

BALATON Zoltan (2):
     ppc/pegasos2: Allow setprop in VOF
     mv64361: Remove extra break from a switch case
