I am giving the explanation why all cross build architectures work, 
except arc.

It does matter. Your solution works at build time, but it doesn't work 
at runtime. Something has to provide the kernel headers for the cross 
glibc and cross compiler to work. In the past it was 
linux-libc-dev-arc-cross and libc6-dev-arc-cross depends on it for that 
purpose.

Therefore I see two options:
- linux-libc-dev provides the arc kernel headers
- cross-toolchaine-base-ports continues to build 
  linux-libc-dev-arc-cross
