Right.

I built without -fno-gcse and noticed that execve() and its variants had
problems -- specifically, tar wouldn't spawn gzip and getty wouldn't
spawn login.

I recompiled libc with -fno-gcse and the problem went away.

I then sent a message to tech-toolchain and port-mips asking for help,
but no response.  Since I noticed the problem, I guess I volunteered to
fix it :)

I've not narrowed it down any further than that -- I think/hope the problem
is in arch/mips/gen.

Yes.  No other problems noticed.
