A hidden symbol gets placed in the dynamic symbol table (as local) if referenced
from a shared library. The right behavior should be to issue an error.
$ cat foo.c
int foo() __attribute((visibility("hidden")));
int foo () { return 42; }
int main() { return foo(); }
$ cat bar.c
int bar() { return foo(); }
