Subject: [PATCH 3/4] gc-libgcrypt: fix assignment error due to
 -Werror=pointer-sign

This fix resolves the following build failure:
lib/gc-libgcrypt.c: In function 'gc_hash_read':
lib/gc-libgcrypt.c:460:14: error: pointer targets in assignment differ in signedness [-Werror=pointer-sign]
       digest = gcry_md_read (ctx->gch, 0);
              ^

* lib/gc-libgcrypt.c: Cast the return value.
