I was not able find in the entire thread answer to my issue, but there is mentioned similar one.
On my Librem 15v3 with Ubuntu 16.04 Lts the result of the build is the warning. I have put echo lines in the script in order to check the SHA1 hashes comparisons and there is difference.
There is the output:
The ME region can be reduced up to:
Setting the HAP bit in PCHSTRP0 to disable Intel ME…
Checking the FTPR RSA signature… VALID
Done! Good luck!

Can you suggest next steps?
