Hmm, yes, libc versioning is disabled. I looked at the libpthread/libthr.
Then, why versioning for threaded libraries is on ?

BTW, as far as I know, there is technical possibility to declare the
"unspecified" version for the symbol (like
	.symver	XXX_old,XXX@
), but I agree that deciding when to do that when libc.so.7 already
broke the ABI in unknown locations is too hard.
