The problem was introduced by commit "mm: variable length argument
support" (b6a2fea39318e43fee84fa7b0b90d68bed92d2ba)
as it didn't update fs/binfmt_aout.c like other binfmt's.

I noticed that on alpha when accidentally launched old OSF/1
Acrobat Reader binary. Obviously, other architectures are affected
as well.
