Allow use of dash as /bin/sh

We've had the check for dash as /bin/sh for a long time. Dash has been
around long enough now that most major issues have been identified and
fixed from  build perspective.

This patch fixes a bashism in the openjade-native recipe. It also
adjusts libtool so that the header at the script is used and not the
value of $SHELL. This is because many Makefiles change $SHELL so dash
can get used to execute what is otherwise configured as a bash shell
script. Since we don't need to execute scripts this way on any system I'm
aware of us building upon, the simplest fix is just to remove $SHELL.

With these two changes the dash check can be removed and we can allow
builds with dash as /bin/sh

[Note: I know I need to add the description of the libtool change above
into the prefix.patch]
