Since the vDSO shared librares on Linux and FreeBSD are called

differently, the initialization order check fails on FreeBSD.

This patch fixes it by ignoring [vdso] instead of linux-vdso.so.

GCC gets the original file from the LLVM Project, so this patch should

probably be upstreamed directly to the LLVM Project rather than to GCC.
