+Subject: Fix link failure on big-endian platforms.
+
+On powerpc64 tests failed as:
+
+```
+ Failed 2/2 subtests
+ ===( 2;0 0/? 0/? 0/? )=========================================Can't load '.../Digest-GOST-0.06/blib/arch/auto/Digest/GOST/GOST.so' for
+ module Digest::GOST: .../Digest-GOST-0.06/blib/arch/auto/Digest/GOST/GOST.so: undefined symbol: rhash_u32_swap_copy at /usr/lib64/perl5/5.24.3/powerpc64-linux/DynaLoader.pm line 193.
+```
+
+rhash_u32_swap_copy() is a function local to this package.
+Seems to be used only for big-endian case.
+
+The fix is to add missing 'src/byte_order.c' file.
+
+All tests pass with patch applied.
