Fix running linux binaries linked against newer glibc. Without
it they segfault on startup in a hard to reproduce way - try running
"/bin/echo 1 1 1 1 1 1" with varying amounts of "1"s; first do
"sysctl compat.linux.osrelease='5.0.0'".
This is obviously not committable as it is. I hope someone can provide a plausible explanation, or even a proper fix.
