--- Comment #23 from Joshua Kinard <kumba at gentoo dot org> ---
I ran into this on a Linux/mips64 (MIPS-IV ISA) build as well, running N32 ABI.

This is in the 'all-stage1-gcc' stage from 'stage1-bubble'. I did not see any
'ld' warnings prior to that, but I have this in dmesg:
[47163.043326]
do_page_fault(): sending SIGSEGV to genmatch for invalid read
access from 0000000000000000
[47163.043354] epc = 0000000000000000 in

[47163.043436] genmatch[10000000+90000]
Running a 64KB PAGE_SIZE, too, if that matters. I'll try to reverse commit
r218976 from Comment #11 to see if that resolves the issue for me as well and
update later.
