Since commit 269a535ca9 ("modpost: generate vmlinux.symvers and
reuse it for the second modpost"), with CONFIG_MODULES disabled,
"make deb-pkg" (or "make bindeb-pkg") fails with:
find: ‘Module.symvers’: No such file or directory
If CONFIG_MODULES is disabled, it doesn't really make sense to build
the linux-headers package.

These have been required by the Debian policy for a while, even though
the tooling can detect and workaround their omission, but are a hard
requirement when using rootless builds.
[masahiro:
The following Debian policy is particularly important for rootless builds:
"Both binary-* targets should depend on the build target, or on the
appropriate build-arch or build-indep target, so that the package is
built if it has not been already."

Cross compiling the x86 kernel on a non-x86 build machine produces
the following error when CONFIG_UNWINDER_ORC is enabled, regardless
of whether libelf-dev is installed or not.
dpkg-checkbuilddeps: error: Unmet build dependencies: libelf-dev
dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting

Since this is a build time dependency for a build tool, we need to

Debian-based distributions place libc header files in a machine

Thus it would be more foolproof to explicitly use 1.0 (as we always
did) than to rely on dpkg-source's defaults.
* In a similar vein, debian/rules is not made executable by mkdebian,
and dpkg-source warns about that but still silently fixes the file.
Let's be explicit once again.

This will be a little more efficient since unset CONFIG options are
stripped away from auto.conf, and we can hard-code the path to auto.conf
since it is never overridden.
include/config/kernel.release is generated before %pkg is run.
So, it is guaranteed auto.conf is up-to-date.

This might be a kind of bike-shed, but I personally prefer grep'able
code.
I often do 'git grep CONFIG_FOO' instead of 'git grep FOO' when I
want to know where that CONFIG option is used.
This makes code longer, but I hope this is acceptable level.

bison/flex is now needed always for building for kconfig. Some build
dependencies depend on kernel configuration, enable them as needed:
- libelf-dev when UNWINDER_ORC is set
- libssl-dev for SYSTEM_TRUSTED_KEYRING
Since the libssl-dev is needed for extract_cert binary, denote with
:native to install the libssl-dev for the build machines architecture,
rather than for the architecture of the kernel being built.

Since commit b41d920acf ("kbuild: deb-pkg: split generating packaging
and build"), the build version of the kernel contained in a deb package
is too low by 1.
Prior to the bad commit, the kernel was built first, then the number
in .version file was read out, and written into the debian control file.
Now, the debian control file is created before the kernel is actually
compiled, which is causing the version number mismatch.
Let the mkdebian script pass KBUILD_BUILD_VERSION=${revision} to require
the build system to use the specified version number.

There is multiple issues with the genaration of maintainer string
It uses DEBEMAIL and EMAIL enviroment variables, which may contain angle brackets,
creating invalid maintainer strings. The documented KBUILD_BUILD_USER and
KBUILD_BUILD_HOST variables are not used. Undocumented and uncommon NAME
variable is used. Refactor the Maintainer string to:
- use EMAIL or DEBEMAIL directly if they are in form "name <user@host>"
- use KBUILD_BUILD_USER and KBUILD_BUILD_HOST if set before falling
back to autodetection
- no longer use NAME variable or the useless Anonymous string
The logic is switched from multiline if/then/fi statements to compact
shell variable substition commands.
