In config.guess triples, the second element is a no-op. powerpc64-elfv2-linux-gnu, powerpc64-unknown-linux-gnu, powerpc64-redhat-linux-gnu are all the same thing. Using a triple 'powerpc64-elfv2-linux-gnu' would be misleading for everyone, because - as you have shown - it does not define _CALL_ELF=2. I am talking about ABIs, as classified by the gnulib module 'host-cpu-c-abi' [1]. In this domain, powerpc64-elfv2 is different from powerpc64. Finer classifications would be possible, depending on processor architecture (e.g. x86 with and without SSE instructions). However, only few packages (e.g. GNU gmp) need this. For GNU Lightning, this ABI classification should be sufficient.
