Well, it's not going to be anything before 2.19, regardless of what
unofficial versions may be in use, so the normal practice is to use 2.19
as base symbol version. Similarly, arch_minimum_kernel should be set to
the kernel.org kernel version where support for LE went in upstream,
without regard to any non-upstream kernel versions people might previously
have used with LE - though failing to have that set is simply a missed
optimization, it doesn't break compatibility if arch_minimum_kernel gets
set later. (By way of comparison, x32 uses 2.16 as minimum symbol
version, although some earlier versions were used before support was
merged into official glibc. I notice we seem to be missing an
arch_minimum_kernel setting for x32; that's a deficiency, it should be set
to 3.4.0 in that case.)
