[stgt] [PATCH 1/2] embed version number in tgtd and tgtadm

[FUJITA Tomonori]

If you compile the git tree, you get:

fujita at lily:~/git/tgt/usr$ ./tgtadm -h
Usage: tgtadm [OPTION]
Linux SCSI Target Framework Administration Utility, version 0.9.2-git-9f4cbd1


If you compile a release version (or on a box without git installed),
you get:

fujita at lily:/tmp/tgt-0.9.2/usr$ ./tgtadm -h
Usage: tgtadm [OPTION]
Linux SCSI Target Framework Administration Utility, version 0.9.2
