GCC does not appear to provide a builtin sincos() as far as I can see.
At any rate, I discovered we lacked a generic sincos() when an Alpine
x86-64 builder failed to build graphviz, so there is definitely no
sincos() there, provided by GCC or otherwise.
I intend to add the remaining complex math functions later this week,
and see where we stand regarding generic math functions. Having a
fully functional libm (at least in practice) is obviously desirable.
