SYMVER_ENABLED is an experimental feature. I suspect the new code in
rtld somehow prevents it from overriding dummy symbols in libc.
SYMVER_ENABLED changes in rtld are work in progress and until they are
finalized, you are on your own.

P.S. "Missing" symbols in rtld are intentional as all not important
symbols are not being suppressed by the symbol map file.
