bug#47382: runtest doesn't work with Solaris 10 /bin/sh

[Rainer Orth]

When trying DejaGnu 1.6.3 rc1 on Solaris 10, it failed immediately with:

runtest: syntax error at line 43: `execpath=$' unexpected

The script hardcodes #!/bin/sh, but the Solaris 10 /bin/sh is
effectively the old Bourne Shell and doesn't support $().

There are several options, I believe:

* Substitute a shell that does (like /bin/ksh in the Solaris 10 case).

* Rework the script to avoid the construct.

* Give up in horror and declare Solaris 10 unsupported, preferably with
  a decent error message at configure time.
