It was added after newlib 1.20.0. The RTEMS Community worked to get
in newlib math the newest from FreeBSD.

You really want to use the RTEMS Source Builder (RSB). It is a tool
written in Python
that knows the versions, patches, locations, and how to build each
target. It can
also build some simulators and it has an initial attempt at starting to
add building
libraries for a specific BSP.
