Add the leading "--" here?
I didn't look to see what other NEWS entries do.

I would much rather have this kind of information in the Makefile.  I
know gdb doesn't always do that right now -- but the current way is kind
of bad IMO.

We can use GNU make features, so it's not hard to transform a list of
formats like "elf xcoff" into a list of variable references like
"$(elf_OBJS) $(xcoff_OBJS)"

Guinevere> diff --git a/gdb/configure.format b/gdb/configure.format

Then we wouldn't need this file, either.
