Compile vismain with -fPIE and link with -pie
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. [BZ #17711] * elf/Makefile (tests): Add vismain only if PIE is enabled. (tests-pie): Add vismain. (CFLAGS-vismain.c): New. * elf/vismain.c: Add comments for PIE requirement.
