I don't see it as more inclusive than using GLIBC_2.19, given that it's 
easy to build a 2.17 or 2.18 glibc with GLIBC_2.19 symbol versions.  (As 
far as I can tell, no symbols got new versions for powerpc64 BE (at least) 
because of a change of semantics in 2.18 or 2.19, so you don't need to 
backport any changes of semantics to ensure binaries built against such a 
2.17 or 2.18 really are compatible with 2.19.)
