This tells automake to store the objects in subdirectories of the top
build directory, not what the top build directory is.

I can't find any documentation on the argument of AM_PROG_CC_C_O, or
AC_PROG_CC_C_O to which it refers. Can anyvody enlighten me?

Because you invoke ./configure in your top source directory, this
directory will also become your top build directory. To use a different
top build directory do

$ mkdir path/to/top/build/directory
$ cd path/to/top/build/directory
$ abs/or/rel/path/to/top/source/directory/configure
$ make

`make` should always be invoked in the build directory. In your case this
is the same as the source directory (see above), so this result is
correct.

Hope this helps.
