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.

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.
