Yes Libnettle has arm assembler routines but they may only support
a minimum of archv5, so there is an option to use C routines that
are compiled to the gcc default of archv3. The gcc assembler 
obviously just assembles what it is told to without warnings.

The openSSL library has assembler routines that support archv4 
and the curl I compiled with this library works on the SA RiscPc,
one step further back than Nettle, like Nettle it has a no-asm option
to just use C routines for older hardware.

I also uploaded the RiscPC(and older) safe libnettle.a so you can build
your own RunImage if you need to.

When I upgraded my fetchmail to openssl1.1.1 there were changes
required in the config but I found examples to help.
It stops ssl3 from being used. (no sslx support in openssl1.1.1)
