When building the aicasm with gcc 10.2 + gas 26.1
Multiple definitions of global variables cause these errors.

multiple definition of `args';
multiple definition of `yylineno';

args came from the expansion of
STAILQ_HEAD(macro_arg_list, macro_arg) args;

The definition of the macro_arg_list structure is needed.
The global variable 'args' is not, so delete.

yylineno is defined by flex, so defining it in bison/*.y
file is not needed, so delete.
