maintainer-clean and yacc/lex files

[Allan Saddi]

Hi there,

It seems that maintainer-clean doesn't delete generated yacc/lex
files correctly. If "parser.y" and "lexer.l" are defined in the
source, maintainer-clean attempts to delete "parserc",
"parserh", and "lexerl". It should delete "parser.c",
"parser.h", and "lexer.c" instead.

The following patch corrects this.

Thanks.
