Files suffixed by .lex.c, .tab.[ch] are generated lexers, parsers, respectively. Clean them up globally from the top Makefile. Some of the final host programs those lexer/parser are linked into are necessary for building external modules, but the intermediates are unneeded. They can be cleaned away by 'make clean' instead of 'make mrproper'.
