You can link against vdso.so if you want to; the kernel build

provides an option to install that image.  Doesn't mean that any
particular libc uses it.

I'd be rather surprised if anyone does this, given the generally
spotty state of vdso.so installation and that there's no such thing as
an ELF import library.

Also, the vdso's clock_gettime isn't actually compatible with
glibc/POSIX -- the return value and errno handling don't match.
