Check if assembler is compatible with AMD64 assembly implementations
* cipher/blowfish-amd64.S: Enable only if
HAVE_COMPATIBLE_GCC_AMD64_PLATFORM_AS is defined.
* cipher/camellia-aesni-avx-amd64.S: Ditto.
* cipher/camellia-aesni-avx2-amd64.S: Ditto.
* cipher/cast5-amd64.S: Ditto.
* cipher/rinjdael-amd64.S: Ditto.
* cipher/serpent-avx2-amd64.S: Ditto.
* cipher/serpent-sse2-amd64.S: Ditto.
* cipher/twofish-amd64.S: Ditto.
* cipher/blowfish.c: Use AMD64 assembly implementation only if
HAVE_COMPATIBLE_GCC_AMD64_PLATFORM_AS is defined
* cipher/camellia-glue.c: Ditto.
* cipher/cast5.c: Ditto.
* cipher/rijndael.c: Ditto.
* cipher/serpent.c: Ditto.
* cipher/twofish.c: Ditto.
* configure.ac: Check gcc/as compatibility with AMD64 assembly
implementations.

Later these checks can be split and assembly implementations adapted to handle
different platforms, but for now disable AMD64 assembly implementations if
assembler does not look to be able to handle them.
