fix "unkown" typos
Makefile fixes

The root Makefile's all target had 'eclipse' as prerequisite. This lead
to an conditioni that the sub-Makefile's 'shared' target was called
twice. Leading to link already exists error messages when creating the
symlinks.

Another problem was with transport-xmpp/Makefile, which called
asmack.sh, which again called the Makefile. This design flaw is now
fixed. asmack.sh does no longer call make.

Minor fix within main/Makefile's clean target.
