If the official kernel source contained a buggy prctl so that it is unsafe
to try prctl on kernels between 2.4.19 and 2.4.21, then linux/configure.in
needs to be changed for 2.4.21 the minimum required kernel version.
Really, having glibc built without --enable-kernel switch just not work
forever no matter what kernel it is running on is a bad idea.
