"Base" version in output of objdump

[Sasha Unknown]

"objdump" dumps unversioned symbols in versioned shared object as having 
version "Base".

Can be ambiguous (e.g. with symbol having version with explicit name 
"Base").

I can write a patch that will cause objdump output unassigned version as 
"*BASE*" (similarly to "*ABS*" and "*UND*" section names); including 
testsuite. Should I? Or would it be too incompatible change?
