Details:

add a lset function

$(lset var_name,value)

function_table_entry
...
  { STRING_SIZE_TUPLE("lset"),          2,  2,  1,  func_lset},


static char *
func_lset (char *o, char **argv, const char *funcname UNUSED)
{
  if(argv[0] && argv[1])
  {
    define_variable(argv[0],strlen(argv[0]),argv[1],o_command,0);
    o = variable_buffer_output (o, argv[1], strlen (argv[1]));
  }
  return o;
}

note, this defines locals in $(foreach ) also :
$(foreach src,$(srcs),$(lset obj,$(subst .c,.o,$(src)))$(info $(obj)))
