Correct behavior. Otherwise, we will get
Symbol table '.dynsym' contains 4 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND
1: 0000000000001000 0 NOTYPE WEAK DEFAULT 7 foo@@v1
2: 0000000000001002 0 NOTYPE GLOBAL DEFAULT 7 foo_v1
3: 0000000000000000 0 OBJECT GLOBAL DEFAULT ABS v1
and the weak foo@@v1 overrides the non-weak foo@v1.
