Update readelf to display the base symbol version as
Symbol table for image contains 5 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND
1: 0000000000003008 0 OBJECT GLOBAL DEFAULT 10 bar@@
2: 0000000000000000 0 OBJECT GLOBAL DEFAULT ABS VERS_1
3: 0000000000003008 0 OBJECT GLOBAL DEFAULT 10 bar@@VERS_1
4: 0000000000003000 0 OBJECT GLOBAL DEFAULT 10 foo@
instead of
Symbol table for image contains 5 entries:

0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND
1: 0000000000003008 0 OBJECT GLOBAL DEFAULT 10 bar

4: 0000000000003000 0 OBJECT GLOBAL DEFAULT 10 foo
That is bar@@ and foo@ vs bar and foo.
