[Bug nptl/5465] New: glibc-2.7 uses vdso symbol in pthread_cond_timedwait when !SHARED

nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S was updated to call
clock_gettime via the VDSO if possible, but that vdso symbol is only provided
for SHARED code (see libc/sysdeps/unix/sysv/linux/x86_64/init-first.c). thus,
linking against libpthread.a and using pthread_cond_timedwait() on x86_64 will
cause a link failure (undefined __vdso_clock_gettime symbol).
the attached patch by Michal Januszewski will only use the vdso symbol when
SHARED is defined.
