[PATCH] do not cat version file if it does not exist

The build process currently produces this ugly message:

 $ make
 cat: version: No such file or directory
 GIT_VERSION = 1.1.GIT
 cat: version: No such file or directory

This patch make GIT-VERSION-GEN check that a file named `version' exists
before trying to cat it.
