lib: Avoid-writing-to-repository-during-install

[Paul Bryan Roberts]

In lib/Makefile, the dummy target "version-stamp" fails to build during 
make install when the git repository in located on an NFS 3 volume for 
which system security policy denies root write access.

During the "install" phase of make install, the make is running as root 
in order to copy executables and so forth from the repository to /usr or 
where ever.  That this involves writing to the repository is 
unexpected.  However, this happens twice as a temporary file is 
generated by the "version-stamp" rule each time the make dependencies 
are checked.

With this patch, "version-stamp" rule does not generate a temporary file 
and so avoids the failure observed when using the NFS volume.  It makes 
a minimum of changes to the existing makefile, avoids bashism and so 
forth while still determining the version stamp only once.

Tested (aka in use) under Ubuntu hardy since Wine 1.1.10.
