What's missing is not only long double complex math, but long double
math at all, unless a target defines double == long double.
An implemenation of the missing long double functions would be most

In theory the imax routines can be easily defined by the target, without
newlib having to do anything. For instance, Cygwin exports strtoll as
strtoimax as well, or llabs as imaxabs.
