I didn't check out as root but it seems a previous 'sudo make install'
messed up the build directory. Chown didn't help, so i deleted the whole
source and checked it out again - problem gone.

Make clean got into and endless loop, had to delete source again :o/

I also took a look at this doc:
http://support.amd.com/us/Processor_TechDocs/32035.pdf
...and decided to add this to the Makefile:

# AMD64
> ifeq ($(TARGET_PLATFORM),x86_64)
> OPT_CFLAGS += -march=k8 -fPIC
> OPT_CFLAGS += -O3 -ffast-math

...which concluded at this:

make[3]: Entering directory

Sadly i don't have the skills to dive into this by myself, so again i'm
hoping for your advice.

Thanks,
