2.57 patch to enhance a message

[Matthias Andree]

Hi,

I have received a bugreport for an autoconf'ed package where the user
complained about autoconf misdetecting a.out vs. ELF format. The package
used autoconf 2.57. The user wasn't aware that autoconf checked the
default output FILE NAME (as opposed to the default output FILE FORMAT)
of the default compiler.

I am suggesting the patch below to remove this ambiguity. I am placing
the patch into the public domain, so feel free to relicense it:
