I removed the eldk-lib stuff, and added the GCCLIBDIR.
Now, it compiles, but doesn't link. A lot of 'undefined reference to'
which I don't understand (they all are about FLTK though).

Thank you for your help already.

PS: I need the -static, but without it, it gives me some more undefined
references to the X-libs.
