What is the problem with this?

And it is easy!

If you have `mypackage' with configure.ac, Makefile.am, sources
etc. then just simply do:

$ cd mypackage
$ mkdir Debug
$ cd Debug
$ ../configure --enable-debug && make all check

and you can build a second configuration:
$ cd ..
$ mkdir Release
$ cd Release
$ ../configure --disable-debug && make distcheck

This is lovely, isn't it? :-)

oki,
