Whether or not this complaint is causing that test to fail, it should be
fixed.

Using an unstripped VDSO image is certainly better than a stripped one,
also for debugging purposes.  However, it needs to be correct (and
complete) -- maybe the VDSO is indeed truncated?   Including full debug
data, the VDSO may be longer than a page, does the kernel actually map
all of it to user space?
