…ing upgrade support. Fixes: az496
… binaries are set +x Debian packages were not having all executable scripts set with the executable bit. Two things could fix this, the first being to properly set the scripts in the original reltool directory. The second is to ensure they were getting set during the debian install, which was happening correctly in the rpm and solaris package managers.
(cherry picked from commit 3cd2274)
Tested on Linux, OSX, OpenSolaris and *BSD. The script still uses /bin/bash but at least now you can easily switch it to /bin/sh if you don't have bash.
