Trouble compiling Syslib of NIOS2 App

What I posted is the 1:1 ouput of "make -n"

The linebreak is already in there.

It is also there for the following commands (which are not executed due to the error):

echo Compiling alt_dcache_flush.c...
and so on...

Could it be connected to the files being included for accessing the HAL ?

Where does this "search and generate the nios-elf-gcc command"-process take place?
