Is it possible to build nss on arm64?

[bob prohaska]

Attempts to compile nss on  a Pi3 running r328436 
stops with

C_Initialize failed: 0x00000030, CKR_DEVICE_ERROR                    
NSPR error code: -5977: Failure to load dynamic library

NSPR error code: -5977: Failure to load dynamic library
gmake[4]: *** [Makefile:92: ../../../dist/FreeBSD12.0_OPT.OBJ/lib/libsoftokn3.chk] Error 1
gmake[4]: Leaving directory '/usr/ports/security/nss/work/nss-3.35/nss/cmd/shlibsign'
gmake[3]: *** [../coreconf/rules.mk:101: libs] Error 2

A Pi 2 running armv7  r328396 finishes without error.

Is there a workaround for arm64 on the Pi3?
