The approach used in GCC, for example in the libquadmath directory, is a 
--enable-generated-files-in-srcdir configure option that is used when 
building a release tarball - so normally the files go in the build 
directory, but a special configuration is used to put them in the source 
directory only when building releases.  (This does not involve the 
"cygnus" option.)  I think support for that seems more generically useful 
(and it makes sense to me for automake to look at features used in other 
packages' configure/build systems, that aren't inherently specific to 
those packages, and try to provide generic versions of them).

The Binutils/GDB release tarball building process is substantially 
different and I'm not familiar with it.
