Backport an upstream-pending patch to fix build on ARM without NEON:

Subject: [PATCH] cipher/sha512: Fix non-NEON ARM assembly implementation
|
|
|
|
* cipher/sha512.c (do_transform_generic)
|
|
[USE_ARM_ASM]: Switch to the non-NEON assembly implementation.

|
|
When building for ARM CPUs that don't support NEON, linking fails
|
|
with an "undefined reference to _gcry_sha512_transform_armv7_neon"
|
|
error. Switching to the non-NEON assembly function corrects this.
