This problem has not been occurring since we have moved aarch32 benchmarking to
a machine with newer kernel.  Closing.

I'm now more of the opinion that this problem is due to the unfortunate stack
layout on older ARMv7 systems.  I.e., LTO increases stack usage, which causes
the process to run out of stack.  I don't think anything needs to be fixed on
GCC side, and, hopefully, we can fix this on our end by upgrading from 3.10
kernel to something more modern.
