Something's wrong with ld-elf.so.1 when SYMVER_ENABLED=true

Hi,
Here's description. It's amd64-CURRENT. World was rebuilt last night (with 
SYMVER_ENABLED=true set in /etc/make.conf long ago). After 
re-installation, sudenly everything's falling on its face with segfaults, 
with "pam_rootok.so not found", with "Can't allocate initial thread" and 
so on. After ld-elf.so.1 and ld-elf32.so.1 were replaced with old ones 
(from Jan 27 :-() everything went and still goes on with no problems.

Indeed, as simple listing (and strings) show, in new (installed => 
stripped) ld-elf.so.1 (180 kB) vs old ld-elf.so.1.old (224 kB) lots of 
symbols (like _DYNAMIC or .rtld_start, for one) are just absent.

Regards,
Vladimir
