It was already removed there ages ago, the only question is whether this
is worth fixing.

The root cause is that these structs seem to have been defined
by people without much knowledge about C alignment.

arm64 is more forgiving, the only affected release architecture
is armhf.

The armel packages could be used through multiarch on all armhf
hardware if someone really needs them.

IMHO the most reasonable action forward would be to do nothing,
and leave this bug open to document that the armhf FTBFS is expected.
