In case if there is no .gitid file we might endup
with build error. Make sure it exist.

Original message from Tycho:
This might be a slightly controversial change since it always causes crtools.h
to be rebuilt, which may be annoying. However, right now version.h is only
generated on the initial git build and never again touched, which is also
incorrect.
We could potentially do something fancy by monitoring .git/HEAD for changes,
but since it may not always exist if building from a tarball, it is a little
sticky.

`git describe` outputs slightly more useful git version info: v1.5-132-ga10f39e
The motivation for this is that we'd like to begin enforcing criu version in
liblxc, but we'd like to enable people to use the git version of 1.6 (since
that has stuff like --ext-mount-map auto), which reports its version as 1.5 but
doesn't tell us the patchlevel as git describe does.

Use true instead of echo >/dev/null -- same effect, less bytes.

Remove space before tab characters.
Found by git grep ' ' (Space, Ctrl-V, Tab in shell).

If criu is built from git repo print git commit id, convenient for debug.
For example
| $ ./criu -V
| Version: 0.7
| GitID: 7985251

Defining it as static char is a bad idea especially
if it get included and never used -- we will get
"unused" variable error.

At moment built-in .SUFFIXES variable is not cleaned
which slows down the building procedure. Add a dummy
rule thus the make won't try to lookup rules for
scripts/Makefile.version (this happens when last
resort rule is used).
Note that this is rather a stub for future convenience
which doesn't affect much current build procedure.

This allows us to have a unique place where version lives
and what is more important other subsystems (such as docs
generation) may reuse version definitions.
At moment EXTRA (which corresponds kernels -rc tag) and
NAME is not yet used, but I desided to put them in place
for future needs.
