[Bug gas/584] New: Invalid relocation to protected symbol

[schwab at suse dot de]

A call to a protected symbols is generating a R_X86_64_PC32 relocation
even though the linker cannot resolve that when generating a shared
library.

$ cat protected.c
void __attribute__ ((visibility ("protected"))) foo (void) {}
void bar (void) { return foo (); }
$ gcc -fPIC protected.c
$ objdump -r protected.o

protected.o:     file format elf64-x86-64
