It's just build/genrecog.c. I had a stale build environment file that was
still sending "-j3" to 'make'. I fixed that and restarted from where it last
left off, and it gets to genrecog.c and spent about

Whatever the issue on MIPS/N32 was, it's resolved by dropping -Wl,-z,now. So
no longer an issue AFAICT.

The problem may be tied to a particular CFLAG on glibc-n32 MIPS. I ran our

and it ended up completing. Difference between

I ran into this too. The problem flag is -foptimize-sibling-calls. You can
pass that with -O1 to trigger the bug, but not with -O0. Some other
optimization in -O1 seems to be mixing with this one and causing the flaw
