This is my sticking point. This explanation is not detailed enough.
*WHY* is the symbol version missing? Why does the version of gcc
that compiled glibc affect the set of symbols exported from glibc
in any way?

Because I thought all existing glibc ports did things the same way
that x86 did, and that even if they didn't, that it didn't make any
difference what version tag was attached to these symbols.
