It's not impossible to run that glibc with early kernels, it's just
that chown() returns ENOSYS.
I claim that this is correct behaviour; chown() is really not
supported on those kernels.
I know this is bad. I will probably end up using a user-space
emulation of chown() (which is also bad, but in a different and far
more interesting way). Then libc will behave the same on all kernel
versions.
