linux: Enable vDSO for static linking as default (BZ#19767)
This patch assumes static vDSO is supported as default, it is now supported on all current architectures that support vDSO. It allows removing both ALWAYS_USE_VSYSCALL define, which an architecture requires to explicit define and USE_VSYSCALL (which defines vDSO only for shared or if architecture defines ALWAYS_USE_VSYSCALL). Checked with a build against all affected ABIs. [BZ #19767] * sysdeps/unix/sysv/linux/aarch64/sysdep.h (ALWAYS_USE_VSYSCALL): Remove definition. * sysdeps/unix/sysv/linux/arm/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/riscv/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (ALWAYS_USE_VSYSCALL): Likewise. * sysdeps/unix/sysv/linux/x86/libc-vdso.h: Remove #if USE_VSYSCALL. * sysdeps/unix/sysv/linux/sysdep-vdso.h: Likewise. * sysdeps/unix/sysv/linux/sysdep.h (ALWAYS_USE_VSYSCALL, USE_VSYSCALL): Remove defitions.
