[ECOS] bug report: tclsh update for freebsd

[Chuck McManis <ecos at mcmanis dot com>]

When using FreeBSD the code :

#!/bin/bash
# restart using a Tcl shell \
    exec sh -c 'for tclshell in tclsh tclsh83 cygtclsh80 ; do \
            ( echo | $tclshell ) 2> /dev/null && exec $tclshell "`( 
cygpath -w \
"$0\" ) 2> /dev/null || echo $0`" "$@" ; \
        done ; \
        echo "heapgen.tcl: cannot find Tcl shell" ; exit 1' "$0" "$@"

In $PACKAGES/services/memalloc/common/current/src/heapgen.tcl fails to find 
the TCL shell because none of those names map to the one installed on the 
system. I added "tclsh8.4" to the line and that fixed it for my install.

In the future, this value should be generated by the configure command in 
the sources somewhere so that this script can pick up the installed TCL 
(and version) as configured. The workaround is to add the name of your 
installed tclsh into this script.
