Hm, I thought that was only in 2.6, and not a lot of people are using
2.6 already, also it seemed easy to check within glibc. If it is in
2.4, too, I don't mind using ELF_PLATFORM. OTOH, I will then have to
use strcmp to find the correct strlenpair table entry, so it won't
really be much easier.

Those don't seem very important, but pca56 would be nice.
