[PATCH] Require bash shell for symlink-mesa.sh

[Dan Nicholson]

The symlink-mesa.sh script has a few bashisms, but is currently invoked
through /bin/sh. This is a problem if /bin/sh isn't bash. Instead,
require bash and use it to process symlink-mesa.sh.

 Alan, does this still work for you on Solaris?
