use compiler builtins for variadic macros when available
this slightly cuts down on the degree musl "fights with" gcc, but more importantly, it fixes a critical bug when gcc inlines a variadic function and optimizes out the variadic arguments due to noticing that they were "not used" (by __builtin_va_arg). we leave the old code in place if __GNUC__ >= 3 is false; it seems like it might be necessary at least for tinycc support and perhaps if anyone ever gets around to fixing gcc 2.95.3 enough to make it work..
