I don't know what's up with the bisection, but I think this is a
configuration problem in your test setup.  You've configured with:

CONFIG_LEGACY_VSYSCALL_NONE=y

which is not valid when you're running binaries that are compiled with
as old a glibc as you're using.  *Dynamic* glibc binaries have been
fine for a long time, but static glibc binaried (e.g. your init, I
presume) need a glibc that's only a couple years old.

You could fix it by either disallowing that particular configuration
or by updating your distro.

OK, I'll disable that configuration since I'm running various
tiny/large modern/legacy OS images (yocto, openwrt, ubuntu, debian,
RHEL) for doing kernel tests.
