There are Library dependencies missing: libld-l4 lib4re-util libuc_c 
lib4re libl4util libl4sys.

Although, the .a files exist.

Nevertheless, i can't find any .pc file in obj/pc/ for this libs; 
opposite to the other REQUIRED_LIBS that the make-process does find.
I don't know, why .pc files haven't been built.


Btw, i had to build libld-l4.a. By default, it only sets 
TARGET=libld-l4.so

Have you tried this before?
I don't get any output from LD_DEBUG.


Thanks again,
