Sometimes people do have this kind of old hardware and kernels, that
is mainly the reason why I came across this problem. That said, the
FAQ mentioned the supported versions
(https://www.busybox.net/FAQ.html#kernel) which are now Linux >= 2.4.x
and glibc >= 2.2, so for that reason, I thought that this patch would
have a chance to get accepted. Raising the minimally supported
versions would be somewhat contradictory to what this commit tries to
resolve, but it's also not on me to decide on where the line is drawn
of what is supported.
