Indeed.  The new method relies on explicitly setting $PATH to the
actual build or install directory, and not on any individual symlink
in the testsuite subdirectory.  "#! stap" is not really appropriate,
since it lacks a full path.

The solution is to not treat those files as shell scripts, and just
run them via "stap [OPTIONS] transok/five.stp".  The OPTIONS need
to be pulled out of the .stp file.

Another solution would be to slightly rewrite all the stp files to be
proper shell scripts, perhaps like this:

   #! /bin/sh
   exec stap [OPTIONS] -e - << 'END'
   SCRIPT
   END
