[PATCH libgcrypt 1/2] 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.

(Resending this in case it wasn't delivered due to not being subscribed.)
