Presumably, _target_os is defined even if the --target flag does not
specify it, but it is better to make it explicit.

Change the source package name from 'linux-$(KERNELRELEASE)' to
'linux-upstream'.
Initially, I tried to use 'linux' to be aligned with the Debian
kernel package, but Ben suggested 'linux-upstream' so that it is
clearly distinguished from distribution packages. [1]
The filenames will be changed as follows:
[Before]
linux-5.12.0-rc3+_5.12.0-rc3+-1.dsc
linux-5.12.0-rc3+_5.12.0-rc3+.orig.tar.gz
linux-5.12.0-rc3+_5.12.0-rc3+-1.diff.gz
[After]
linux-upstream_5.12.0-rc3+-1.dsc
linux-upstream_5.12.0-rc3+.orig.tar.gz
linux-upstream_5.12.0-rc3+-1.diff.gz
Commit 3716001bcb7f ("deb-pkg: add source package") introduced
KDEB_SOURCENAME. If you are unhappy with the default name, you can
override it via KDEB_SOURCENAME.

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp.
GZIP, BZIP2, LZOP env variables are reserved by the tools. The original
attempt to redefine them internally doesn't work in makefiles/scripts
intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in
broken builds. There can be other broken build commands because of this,
so the universal solution is to use non-reserved env variables for the
compression tools.

Allow user to use alternative implementations of compression tools,
such as pigz, pbzip2, pxz. For example, multi-threaded tools to
speed up the build:
$ make GZIP=pigz BZIP2=pbzip2
Variables _GZIP, _BZIP2, _LZOP are used internally because original env
vars are reserved by the tools. The use of GZIP in gzip tool is obsolete
since 2015. However, alternative implementations (e.g., pigz) still rely
on it. BZIP2, BZIP, LZOP vars are not obsolescent.
The credit goes to @grsecurity.
As a sidenote, for multi-threaded lzma, xz compression one can use:
$ export XZ_OPT="--threads=0"

Add a 'dir-pkg' target which just creates the same directory structures
as in tar-pkg, but doesn't package anything.
Useful when the user wants to copy the kernel tree on a machine using
ssh, rsync or whatever.

Some "make help" text lines extend beyond 80 characters.
Wrap them before an opening parenthesis, or before 80 characters.

scripts/package/Makefile does not use $(obj) or $(src) at all.
It actually generates files and directories in the top of $(objtree).
I do not see much sense in descending into scripts/package/.
