This doesn't explain why. This patch is needed to prevent the use of
the assembly
versions of some methods in newlib which are incorrect for ilp32. This
can be removed
when those methods are updated from ARM. Newlib is quite behind ARM for these
methods and that will require work from an ARM Newlib person.

Updates #4215,

Improve the comment and ensure the ticket is clear that this is temporary for
those reasons.

Looks like you forgot to use sha512-base64
