Thanks for your help, but i do not think that deleting subdirectories
from the ecosSWtools source directory would do fine. I tried this and
got error messages from configure about missing subdirectories and so on.
Therefore i think you better delete the tools you do not want to build
from either the Makefile or even better from the configure.in file
(host_libs and host_tools section). Therefore my question, if you have
to take into account any dependencies, as for example do some of the
target tools need some of the host tools or host libs already built?
