For 7.0: 
- make sysroot directory with all headers and libraries used
  and put "--with-sysroot=XXX" as parameters of configure-scripts
- Add "--disable-werror" to configure of binutils2.17
- Add above and "--disable-initfini-array" to configure of gcc
=> This worked for me, but unfortunately doesn't for 8.0.

It seems compilation works, because I can run compiled kernel-objects.
But for userspace programs linked to libraries I get ld-elf.so undefined
symbol... errors.

Maybe you have some ideas to solve this.

I already tried to use gcc-source from "/usr/src/contrib/" which doesn't
work, too.

Marc
