EDE: make project shared objects

[Sascha Wilde]

The following patch addresses a bunch of issues: 
- Some incarnations of libtool (namely the one in Debian Lenny) need
  --tag even in this simple case
- We use the libtool .lo object extension, so we no longer interfere
  with the default rules for non shared objects
- Added missing -c for object generation
- Removed LTLINK var definition from compiler, this belongs only to the
  linker definition.
- Fixed the linker definition: there was CPP used, but linking is not
  done by the preprocessor...  :)

It should be transferred to the libtool based c++ compiler/linker
definitipon, too -- but I'm no c++ guy, so I would like to leave this to
someone who is willing/able to test it...  ;-)

FWIW: Linking against libs in make projects still doesn't work.  I'll
have a look t this next...

cheers
