gzip from busybox does not understand the '--best' command line option.
Use '-9' instead which is understood by all gzip flavours (checked with
GNU, BSD and busybox).

Except for some minor saving in disk space, stripping the binaries
doesn't bring any benefits and it might prevent us from getting usable
debugging information even from binaries build with DEBUG not set. Most
distributions will strip the binaries as part of their packaging process
anyhow.
If someone really wants stripped binaries as a result of the netsniff-ng
build, they could still add '-s' to CFLAGS or call strip manually.

Ever since we switched to the hand-crafted ./configure script, support
for cross-compiling the netsniff-ng toolkit was basically broken.
Restore the abaility to cross-compile our tools by making ./configure
consider the CROSS_COMPILE and SYSROOT variables.
Example for cross-compiling on arm:
$ CROSS_COMPILE=arm-linux-gnueabihf- \
SYSROOT=/usr/arm-linux-gnueabihf \
./configure
$ make
assuming the cross-compiled libraries (and their respective pkg-config
information) are in /usr/arm-linux-gnueabihf.

In order to be able to set the (sort of) standard command variables CC,
LD etc. from configure via Config, rename the silent LD command variable
to LDQ, in accordance with the existing CCQ.

Otherwise we get

Don't reset the variable CC in the Makefile, but set it to gcc by
default (can be overriden when e.g. compiling with `make CC=clang').
This way we can also have non-verbose compiles with compilers other than
gcc. Furthermore make sure that the CC variable is also respected for
LD.

Similar to the 'make C=1' for the Linux kernel, wire up the sparse
command for our build system in a similar fashion. Use 'make C=1 [tool]'
to check the source files using sparse. Of course, the sparse tool needs
to be installed and available in your $PATH for this to work.

Follow up for commit 311d4376 ("build: Make sure we get the correct
previous tag for the changelog").
Move getting the previous tag into an own command and use it where
appropriate.

When going from an -rc release to a stable release (e.g. v0.5.8 ;-) the
generated shortlog will not be generated from the latest -rc tag but
from the second to last due to the sort order of the tag list:
0.5.5
0.5.6
0.5.7
v0.5.8 <-- newest tag
v0.5.8-rc1
v0.5.8-rc2
v0.5.8-rc3
v0.5.8-rc4
v0.5.8-rc5 <-- second newest tag
Thus use 'git describe' to get the proper previous tag.

On Debian/Ubuntu systems, /bin/sh is /bin/dash which doesn't understand
the -e option to the `echo' builtin. Thus the build output looks
something like the following:
Building netsniff-ng toolkit (0.5.8-rc5+) for x86_64-linux-gnu:
Building netsniff-ng:
-e CC dissector.c
-e CC dissector_eth.c
-e CC dissector_80211.c
...
Prevent this by setting SHELL to /bin/bash if it exists on the system,
otherwise stick to /bin/sh.

Add a Makefile target to build and upload a snapshot of netsniff-ng to
the Coverity scanner. The variables COV_EMAIL and COV_PASSWD need to be
set accordingly:
make coverity COV_EMAIL=tklauser@distanz.ch COV_PASSWD=...
Currently the sub-make which is part of the cov-built call issues
warnings about undefined variables from the template. This can be
ignored, the build works just fine.

Fix them up so that a proper changelog can be generated automatically.
Also while at it, add two "hidden" targets that can be used to test
their output.

We have recently changed VERSION_STRING to append CONFIG_RC at the
end of the string. Thus, for the build system, change it to
VERSION_SHORT where needed, e.g. in release targets where the "+"
appendix is not wished.

Split the build system into smaller manageable pieces, grouped by
context. In that sense, we can keep the most important information
within the Makefile itself, and group out misc bits and pieces that
we just include into it. E.g. 'Cmds' contains all defined commands
that we call from other locations, 'Template' contains the generic
build template for all tools, 'Extra' has pieces that need special
treatment for the tools to build and 'Misc' contains help and release
code. This makes it more manageable on the long run. While at it, I
also simplified some code and removed all Wflags expect "-Wall" as
we want to convert into "-Wall -Wextra -W" anyway.
