    tests: fix spurious failure due to Solaris XPG4 sh bug
    
    On Solaris 10, the /usr/xpg4/bin/sh shell seems unable to execute
    a shell script named 'script':
    
      $ touch script
      $ /bin/sh script; echo status: $? # As expected.
      status: 0
      $ /usr/xpg4/bin/sh script; echo status: $? # Weirdness follows.
      /usr/xpg4/bin/sh: script: cannot execute
      status: 1
    
    This was causing a spurious testsuite failure for users which have
    /usr/xpg4/bin in $PATH before /bin and /usr/bin.  Fix that.
    
    * tests/m4sh.at (Configure re-execs self with CONFIG_SHELL): Rename
    the m4sh-produced script to 'script2', to avoid the just-described
    issue.
