Subject: Fix running the qtcreator script with traditional Bourne shell.

First, there's no $( ) for subshells. You have to use backticks.

Second problem, "VAR=value exec command" doesn't work. Split into
variable setting, exporting and then exec'ing the program.

Third, Solaris doesn't come with readlink, so parse the output of ls -l.
