When building the LINUX_COMPILER definition, instead of merely taking the last
line from "$(CC) -v", grep for ' version ' in the output. This supports both
gcc and clang.

When using a domain login, `whoami` returns the login in
user\domain format. This leads to either warnings on unrecognised
escape sequences or escaped characters being generated for the user.
This patch ensures that any backslash is escaped to a double-backslash
to make sure the name is preserved correctly. This patch does not
enforce escaping on the KBUILD_BUILD_USER variable, as this is something
the user has control of and can escape if required.

Make it possible to override the user@host string displayed during boot
and in /proc/version by the environment variables KBUILD_BUILD_USER and
KBUILD_BUILD_HOST. Several distributions patch scripts/mkcompile_h to
achieve this, so let's provide an official way. Also, document the
KBUILD_BUILD_TIMESTAMP variable while at it.

Don't test for /bin/{dnsdomainname,domainname}, simply try to execute
the command and check if it returned something.

The mkcompile_h script does `echo` regardless of silent mode the make is
running at, so have it respect $quiet from kbuild and only echo when not in
silent mode.

Introduce KBUILD_BUILD_VERSION to make it
possible to override kernel build version
during build time.

Introduce KBUILD_BUILD_TIMESTAMP to make it
possible to override kernel build timestamp
during build time.

But variables are useful mainly by distros
that want to pass info from an SCM when
building the kernel. Timestamp could be last
checkin date for a file etc.

The idea came from Olaf Hering <olaf@aepfle.de>

Fix a minor bug in mkcompile_h.  As one can see, the current locale is used
while getting the version of gcc.  This produces problems when a locale
other than C or en_US is used.  As an example, my /proc/version contains
Turkish characters in iso-8859-9 encoding.

This patch fixes this issue by making sure that the C locale is used to get
gcc's version.

Add PREEMPT to UTS_VERSION where enabled as is done for SMP to make
preempt kernels easily identifiable.
Added SMP PREEMPT as comment in compile.h to force it to be
updated when they change (sam).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
