hi,
I found that when you missing the mid under GNU Hurd, the GDB's
configure doesn't complain about that.
But you will get a compile error until you do the make.
So I add the check.
By the way, I just check the existence of mig, have not check whether
mig work correct yet.
This is my first time to submit patch, I just build this by git
format-patch. If something wrong, just tell me, I will fix it.
