Update to 5.6.2

* Update buildlink3.mk.

Changelog:
5.6.0 - added AuthenticatedSymmetricCipher interface class and Filter wrappers
      - added CCM, GCM (with SSE2 assembly), EAX, CMAC, XSalsa20, and SEED
      - added support for variable length IVs
      - added OIDs for Brainpool elliptic curve parameters
      - improved AES and SHA-256 speed on x86 and x64
      - changed BlockTransformation interface to no longer assume data alignment
      - fixed incorrect VMAC computation on message lengths
        that are >64 mod 128 (x86 assembly version is not affected)
      - fixed compiler error in vmac.cpp on x86 with GCC -fPIC
      - fixed run-time validation error on x86-64 with GCC 4.3.2 -O2
      - fixed HashFilter bug when putMessage=true
      - fixed AES-CTR data alignment bug that causes incorrect encryption on ARM
      - removed WORD64_AVAILABLE; compiler support for 64-bit int is now required
      - ported to GCC 4.3, C++Builder 2009, Sun CC 5.10, Intel C++ Compiler 11

5.6.1 - added support for AES-NI and CLMUL instruction sets in AES and GMAC/GCM
      - removed WAKE-CFB
      - fixed several bugs in the SHA-256 x86/x64 assembly code:
          * incorrect hash on non-SSE2 x86 machines on non-aligned input
          * incorrect hash on x86 machines when input crosses 0x80000000
          * incorrect hash on x64 when compiled with GCC with optimizations enabled
      - fixed bugs in AES x86 and x64 assembly causing crashes in some MSVC \ 
build configurations
      - switched to a public domain implementation of MARS
      - ported to MSVC 2010, GCC 4.5.1, Sun Studio 12u1, C++Builder 2010, Intel \ 
C++ Compiler 11.1
      - renamed the MSVC DLL project to "cryptopp" for compatibility \ 
with MSVC 2010

5.6.2 - changed license to Boost Software License 1.0
      - added SHA-3 (Keccak)
      - updated DSA to FIPS 186-3 (see DSA2 class)
      - fixed Blowfish minimum keylength to be 4 bytes (32 bits)
      - fixed Salsa validation failure when compiling with GCC 4.6
      - fixed infinite recursion when on x64, assembly disabled, and no AESNI
      - ported to MSVC 2012, GCC 4.7, Clang 3.2, Solaris Studio 12.3, Intel C++ \ 
Compiler 13.0
