"dotnet -h" fails the same way under a netbsd-9 kernel, so this problem
is not related to the futex rewrite that was committed to HEAD last april.
it could be something else wrong or missing in the linux emulation code
that this program happens to notice.

I see that this program tries and fails to find a few shared libraries:
	liblttng-ust.so.0
	liblttng-ust-tracepoint.so.0

and also a procfs file that our procfs does not provide even in linux mode:
	/proc/self/mountinfo

either of those could also be what this program is unhappy about.
