I think we'd be wise to update the host system prerequisites.  My understanding
is that the --enable-kernel= will cause Glibc to omit fallbacks for kernels
older than that.  That could mean that any programs we build against that Glibc
will fail if the host system isn't at the specified version of the kernel or
newer.  At the very least, we'd have to state that the tests depend on the
version of the host system's kernel.
