Expected Behavior

It should use the tools in ../../bin.

Steps to Reproduce

Make sure that the tools are not available; touch one of the lexer or yacc files in the source tree and then run cmb-make.

Fixed for 110.99.5. The fix was to modify cmb-make to update the PATH variable to include the path to the directory containing the sml command. I.e., if you run cmb-make ../../bin/sml, then ../../bin is added to the PATH variable.
