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.
