Inside of libgfortran, I think it should depend on some macro defined

then
#define MATHFUNC(funcname) __ ## funcname ## ieee128
(i.e. use the functions that will be used when one uses e.g.
sinl in C when compiled with -mabi=ieeelongdouble), but I'm not sure
if those need to be declared by libgfortran or math.h declares them).
Otherwise (when libgfortran is compiled against glibc older than 2.32)
it should use
#define MATHFUNC(funcname) funcname ## q
i.e. use the libquadmath APIs).
The current Ubuntu does not have these functions:
ubuntu@gcc-fortran:/lib/powerpc64le-linux-gnu$ nm libm.a 2>/dev/null |
grep ieee128
ubuntu@gcc-fortran:/lib/powerpc64le-linux-gnu$
Will they be supplied in the future, or with the advanced toolchain?
