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.)
