Introduces a helper that used to be open-coded in a bunch of places -
pads the coredump to given alignment.  And switches those places
to that new helper...

FWIW, I haven't tried that on your config yet, but here (with the patch
in my previous mail) I'm seeing a sane-looking coredump -
-rw------- 1 root root 315392 Nov 15 17:48 core
Different userland, presumably, since that static binary is 684349
bytes long.

I'll try to reproduce with your config...
