both pypy and pypy3 (in released versions) trying to access /proc/1/status to detect if it builds on PaX-enabled system.

Unfortunatelly, grsec's CONFIG_GRKERNSEC_PROC feature, or kernel mainline's `hidepid` procfs feature blocks this (build process under portage user can't see pid1).

There is a patch (already merged in VCS version) on the bug's URL that fixes that behavior.
I'm asking that patch to be backported.

Reproducible: Always

Here is pypy buildlog, for example
Same applicable for pypy3

I don't have PaX-enabled systems aymore, but anyway, it should alredy be fixed by new releases.
