Hash test fails on 64-bit big endian CPU architecture

[rogers0]

Hash test fails on 64-bit big endian CPU architecture, such as s390x, ppc64 and sparc64:
/«BUILDDIR»/libcork-0.15.0+ds/tests/test-core.c:341:F:hash:test_hash:0: Unexpected hash value 0xac7d28cc (expected 0x74bde19d)

Build log can be referenced:
https://buildd.debian.org/status/fetch.php?pkg=libcork&arch=s390x&ver=0.15.0%2Bds-1&stamp=1464961690

I tried on debian s390x porterbox. error msg is:
libcork/tests/test-core.c:332:F:hash:test_hash:0: Unexpected hash value 0xac7d28cc (expected 0x74bde19d)

and related code is:
test_hash_buf(BUF, LEN-1,
/* little 32 / 0xba6bd213,
/ big 32 / 0x29d175e5,
/ little 64 / 0xac7d28cc,
/ big 64 */ 0x74bde19d);

so maybe for 64bit Arch, the result is the same as little endian?

Added my result of hash test from s390x on #131
