New description:
The Newlib C Library is missing long double support when the architecture
has long double != double. These are math methods that end in ''l''. See
[https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/math.h.html
math.h] for a complete list.
The [https://github.com/JuliaMath/openlibm openlibm] project appears to
have appropriately licensed implementations and support for many
architectures.
The goal of this project is to port missing long double methods from
openlibm to newlib.
The project can be large or small depending on the number of architectures
that are addressed.
