semicolon separation in LC_ALL is wrong. Either variable needs to be
exported before as a separate commit or set as part of the commit in the
beginning. Used second variant.

This fixes broken build on user's locale setup which makes 'date' binary
to produce invalid characters in rpm changelog (e.g. cs_CZ.UTF-8 'čec'):

$ make binrpm-pkg

pacman is the package manager used by Arch Linux and its derivates.
Creating native packages from the kernel tree has multiple advantages:

* The package triggers the correct hooks for initramfs generation and
  bootloader configuration
* Uninstallation is complete and also invokes the relevant hooks
* New UAPI headers can be installed without any manual bookkeeping

The PKGBUILD file is a modified version of the one used for the
downstream Arch Linux "linux" package.
Extra steps that should not be necessary for a development kernel have
been removed and an UAPI header package has been added.

${DEBFULLNAME-${user}} falls back to ${user} when DEBFULLNAME is unset.
It is more reasonable to do so when DEBFULLNAME is unset or null.

Otherwise, the command:

  $ DEBFULLNAME= make deb-pkg

will leave the name field blank.

The same applies to KBUILD_BUILD_USER and KBUILD_BUILD_HOST.

Set -e to make these scripts fail on the first error.

Set -u because these scripts are invoked by Makefile, and do not work
properly without necessary variables defined.

I tweaked mkdebian to cope with optional environment variables.

Remove the explicit "test -n ..." from install-extmod-build.

Both options are described in POSIX. [1]

Commit d5940c60e057 ("kbuild: deb-pkg improve maintainer address
generation") supported the "name <email>" form for DEBEMAIL, with
behavior slightly different from devscripts.

In Kbuild, if DEBEMAIL is given in the form "name <email>", it is used
as-is, and DEBFULLNAME is ignored.

In contrast, debchange takes the name from DEBFULLNAME (or NAME) if set,
as described in 'man debchange':

  If this variable has the form "name <email>", then the maintainer name
  will also be taken from here if neither DEBFULLNAME nor NAME is set.

This commit removes support for the "name <email> form for DEBEMAIL,
as the current behavior is already different from debchange, and the
Debian manual suggests setting the email address and name separately in
DEBEMAIL and DEBFULLNAME. [1]

If there are any complaints about this removal, we can re-add it,
with better alignment with the debchange implementation. [2]

Commit edec611db047 ("kbuild, deb-pkg: improve maintainer
identification") added the EMAIL and NAME environment variables.

Commit d5940c60e057 ("kbuild: deb-pkg improve maintainer address
generation") removed support for NAME, but kept support for EMAIL.

The EMAIL and NAME environment variables are supported by some tools
(see 'man debchange'), but not by all.

We should support both of them, or neither of them. We should not stop
halfway.
