>From the elf spec:
If different visibility attributes are specified for distinct references to or
definitions of a symbol, the
most constraining visibility attribute must be propagated to the resolving
symbol in the linked object.
The attributes, ordered from least to most constraining, are: STV_PROTECTED,
STV_HIDDEN and
STV_INTERNAL.
You can't have 2 definitions. The above lines apply to cases where there is
only one definition and others are just references.
