No, I am afraid you have misinterpreted the article.

It was (mostly) about compiling a cross-*compiler* and not something
like Samba.  A cross compiler would normally be built on e.g.
x86-linux, be designed to run on x86-linux and target arm-linux.  So
--build would be x86-linux, --host would also be x86-linux and
--target would be arm-linux.

For something like Samba, --target does not make sense, because Samba
is not a compiler/assembler/linker etc.

e.g. the article says: "Naturally, most programs are not cross
compilation tools. For those programs, it does not make sense to speak
of a target. It only makes sense to speak of a target for tools like
`gcc' or the `binutils' which actually produce running code. For
example, it does not make sense to speak of the target of a tool like
`bison' or `make'."  and you can add Samba to "bison" and "make".

--build is where you are building the software.
--host is where the software will be hosted (i.e. where you are going
to run it after compiling it.)
--target is to do with the output that the software you are building
will create.  Obviously not relevant for something like Samba.

--build is normally guessed correctly.
--host defaults to the same as --build, but Hitesh wants arm-linux.
--target (as mentioned several times above ;) does not make sense here.

It's not rocket surgery ;)
