[PATCH] PR dynamic-link/17711: copy relocations against protected symbols don't work

[H.J. Lu]

Protocted symbol in shared library can only be accessed from PIE
or shared library.  Linker in binutils 2.26 enforces it.  We must
compile vismain with -fPIE and link it with -pie.  OK for master?

Thanks.
