It is a good idea to tell the size of vDSO by a PT_LOAD segment.  I
can't figure out a case this doesn't work.  Patch is good me.

Note that I am unable to run the tests on the aarch64 machine where I
reported the problem, because it is stuck in the kernel upgrade.
However, I run your patch on other aarch64 machine.  Your patch does
fixes the fails in vdso-warning.exp.

Thanks a lot for fixing it in different ways.
