This finally creates the libnftables shared object.
For some reason, this causes two compiler warnings to appear:
| parser_bison.y: In function 'nft_parse':
| parser_bison.y:131:3: warning: implicit declaration of function 'nft_set_debug' [-Wimplicit-function-declaration]
| nft_set_debug(1, scanner);
| ^~~~~~~~~~~~~
| parser_bison.c:64:25: warning: implicit declaration of function 'nft_lex' [-Wimplicit-function-declaration]
| #define yylex nft_lex
| ^
| parser_bison.c:4745:16: note: in expansion of macro 'yylex'
| yychar = yylex (&yylval, &yylloc, scanner);
So this patch contains a workaround, namely declaring both functions
in src/parser_bison.y. During linking the objects are found, so this is
rather a matter of cosmetics.
