Moinak Ghosh 26bb137257 Changes for generalized runtime SSE/AVX/XOP detection.
Multi instruction set XXhash build with runtime selection.
Extend CPUID code to detect more instruction sets.
Add options for BLAKE2 hash.
Move GCC builtins into utils header.
Bump file format version number due to extended digest flags.
Add descriptions to digest list.

${prog} [<options>]
<options> can be one of the following:
--prefix=<val> The installation prefix (default: /usr).
--enable-debug Enable debug mode compilation (default: disabled).
--disable-allocator Disable use of internal memory allocator mechanism (default: enabled).
--enable-debug-stats Enable printing of some verbose debug info (default: disabled).
--with-libbsc=<path to libbsc source>
Enable support for libbsc (See: libbsc.com). Full path to the libbsc
source tree must be provided. It links the library statically.
--with-openssl=<path to OpenSSL installation tree> (Default: System)
This defaults to the system's OpenSSL library. You can use this option
if you want to use an alternate OpenSSL installation.
--with-zlib=<path to zlib installation tree> (Default: System)
Enable building against an alternate Zlib installation.
--with-bzlib=<path to Bzip2 library installation tree> (Default: System)
Enable building against an alternate Bzip2 and library installation.
--no-sse-detect Do NOT attempt to probe the system's SSE/AVX capability for build flags.
--use-key256 Use 256-bit encryption keys. Default key length is 128-bit.
--help Display this help message.
