No, this wouldn't work. Those strings ("lex" and "yacc" above) do not
become commands on the filesystem, so they won't be visible to a build
system that's looking for lex or yacc. They are merely used within the
derivation to refer to the inputs.
Implementing John's suggestion would involve installing symbolic links
in /nix/store/*-flex-* and /nix/store/*-bison-* in the flex and bison
recipes, which I guess means adding a new phase to those recipes.
