Move PRERELEASE to mkit.ini

src/include/build.sh

     #
     #  1. use VERSION (from config.mk)
     #  2. if we are in git, override the version with last tag
-    #  3. if set, add PRERELEASE (from config.mk) as pre-release ID
+    #  3. if set, add project:prerl (from mkit.ini) as pre-release ID
     #     (afer dash)
     #  4. if we are at a later commit than the last tag, add branch
     #     name and commit sha1 to build metadata (after plus sign)
     # Examples:
     #
     #     myprog v1.0.7                         # all clear
-    #     myprog v1.0.7-alpha                   # PRERELEASE="alpha"
+    #     myprog v1.0.7-alpha                   # mkit.ini: project:prerl="alpha"
     #     myprog v1.0.7-alpha+g1aef811.master   # ^^ + some commits after
     #     myprog v1.0.7-alpha+gf14fc4f.api2     # ^^ + on a feature branch
     #     myprog v1.0.7-alpha+gf14fc4f.api2.dirty  # ^^ + tree edited
     # meta-data is to *identify* the code, and provide safe path back
     # to tree; commit refs are already perfect for that.
