I try to refactor the sourcecode into a directory structure because the
root directory gets a little bit packed.

The thing I tried to achieve is to collect all the sourcefiles through
the SUBDIRS structure downwards and then in some subdirectory build the
SOURCES variable - and using AC_SUBST it complains that subst is not
allowed to be used in SOURCES. What's the "correct" way to do this?
