Description: Allow overriding git hash in version string with package version
 When compiling cc65, it will place the git hash of the checked out commit in
 the version string which isn't useful when building a distribution package
 since there either won't be an upstream git hash if there is one at all. Make
 it so that if the variable PKG_VERSION is defined when building, its contents
 will be placed into the version string instead of the git hash.
