[PATCH v2] Makefile: don't remove configure on distclean

[Jonas 'Sortie' Termansen <sortie@maxsi.org>]

make distclean conventionally restores the extracted release tarball to
its original distributed contents by cleaning the source code for
distribution. However, the configure script is part of the distribution
and should not be removed. This behavior is creating problems on my
package infrastructure where configure-based packages have make
distclean run afterwards and then the subsequent git build fails.

Add reallyclean for development that also removes configure.

Yeah -- I was thinking you'd want a reallyclean target or something,
but wasn't sure what to call it. Here's a version with reallyclean:
