Title:
  arm64 build doesn't use asm and is 4x-16x slower than it could be

Status in OpenSSL:
  New
Status in openssl package in Ubuntu:
  New

Bug description:
  The openssl build for arm64 doesn't compile in the assembly that is
  present in openssl as of version 1.0.2 for aarch64 because the debian-
  targets.patch that is applied specifies a target that doesn't have
  assembly. The line at issue is debian-arm64 target which needs
  ${no_asm}  changed to ${aarch64_asm}:linux64. Running openssl speed
  -evp aes-128-gcm shows a 4x-16x improvement in performance with this
  change made and the package rebuilt. Other aes and sha variants show
  similar performance gains by enabling asm.
