Normally, you don't need to copy L4 header files. It should be enough
to specify the location of your Pistachio user-land build directory
in your 'build.pistachio_x86/etc/pistachio.conf', for example:

  PISTACHIO_USER_BUILD_DIR = $(HOME)/src/l4ka-pistachio/user/build

This declaration is used for both the location of the L4 headers and
the location of the L4 API-to-ABI library called 'libl4.a'.

Of course, you have to build the Pistachio user land before building
Genode. Could you provide us with the output of 'make core VERBOSE='?
Using this output, we could see the arguments passed to the compiler
and linker.
