Re: [PATCH 1/2] deb-pkg: Add automatic support for armhf architecture

Debian armel userland can be run on any device, so it is suggested to
better rely on toolchain configuration rather than kernel config
symbols.

For arm-gnueabi(hf) toolchain something like:
  $ gcc -dumpspecs | grep multilib_defaults -A2 | grep -q soft && echo
"This is armel"
  $ gcc -dumpspecs | grep multilib_defaults -A2 | grep -q hard && echo
"This is armhf"
could be checked instead.

Best regards
