This is the target for which a package is being compiled. Often used in
rules files because it permits cross compiling. For cross compiling from
linux-i386 to hurd-i386, it will stay the same - i386.

This is the host which is compiling a package.

This is the gnu version of the target architecture - for example when you do
gcc -v on i386 linux it reports:
Reading specs from /usr/lib/gcc-lib/i486-linux/2.7.2.3/specs
So for i386 the gnu build architecture is i486.

To extend it consistently you want some options like:

dpkg --print-installation-os

OS of the target system. linux or hurd.

dpkg --print-gnu-build-os

GNU OS of the target system - linux or gnu.

dpkg --print-os

This should return the name of the host os - similar to uname I think.

Yes, this is important for the hurd.
