Ran into one I cant find an answer for compiling diamond 2.0.5.7 on Ubuntu 16.04 64 bit armv8

ok another new problem: during linking:

build/scrypt_mine.o: In function 'scrypt(void const*, unsigned long, unsigned int*, void*)':
scrypt_mine.cpp: (.text+05c): undefined reference to 'scrypt_core'
collect2: error: ld returned 1 exit status
Makefile:302: recipe for target 'diamond-qt' failed

I give up for tonight, will wait for new wallet source.  diamond.pro or Makefile or src/makefile.unix needs update for armv8 I don't know why I cant figure this out ... tried qmake USE_PNP=1 xARCHCPU=armv7l ...
