1. I want to be able to build it as a normal user.
2. It shouldn't fail in the middle of a 3 hour build just because I am 
not root. I can live with an error message during configure if root is
really required. But it should tell me what to do in order to build it
as a normal user.
3. It shouldn't require $(build_tooldir)/sys-include has to exist. I
only have $(build_tooldir)/include and $(build_tooldir)/lib, similar
to my native glibc setup.
