Minimize yacc and lex output
This minimizes the "make" output from the yacc and lex rules, following the same technique as the rest of the Makefile. The lex rule had a special case to deal with the situation where flex is not available. I don't think this is needed, so I removed it. If flex is truly unavailable, the person building gdb can simply "touch" the output file. gdb/ChangeLog 2018-07-09 Tom Tromey <tom@tromey.com> * Makefile.in (%.c: %.y): Use ECHO_YACC. (%.c: %.l): Use ECHO_LEX. Just fail if flex not available. * silent-rules.mk (ECHO_YACC, ECHO_LEX): New variables.
