Enable VDSO on x86_64 statically linked programs [BZ #19767]
All the required code already existed, and some of it was already running. AT_SYSINFO_EHDR is processed if NEED_DL_SYSINFO_DSO is defined, but it looks like it always is. The call to setup_vdso is also unconditional, so all that was left to do was setup the function pointers and use them. This patch just deletes some #ifdef to enable that. [BZ #19767] * nptl/Makefile (tests-static): Add tst-cond11-static. (tests): Likewise. * nptl/tst-cond11-static.c: New File. * sysdeps/unix/sysv/linux/Makefile (tests-static): Add tst-affinity-static. (tests): Likewise. * sysdeps/unix/sysv/linux/sysdep-vdso.h: Check USE_VSYSCALL instead of SHARED. * sysdeps/unix/sysv/linux/sysdep.h (ALWAYS_USE_VSYSCALL): New. (USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/tst-affinity-static.c: New file. * sysdeps/unix/sysv/linux/x86/libc-vdso.h: Check USE_VSYSCALL instead of SHARED. * sysdeps/unix/sysv/linux/x86_64/init-first.c: Don't check SHARED. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (ALWAYS_USE_VSYSCALL): New.
