Now that the kernel build supports flex and bison, remove the _shipped files and generate them during the build instead. There are no more shipped lexer and parser, so I ripped off the rules in scripts/Malefile.lib that were used for REGENERATE_PARSERS. The genksyms parser has ambiguous grammar, which would emit warnings: scripts/genksyms/parse.y: warning: 9 shift/reduce conflicts [-Wconflicts-sr] scripts/genksyms/parse.y: warning: 5 reduce/reduce conflicts [-Wconflicts-rr] They are normally suppressed, but displayed when W=1 is given.
