Bugfix
   * On Linux on ARMv8, fix a build error with SHA-256 and SHA-512
     acceleration detection when the libc headers do not define the
     corresponding constant. Reported by valord577.
Changelog for building SHA-256 and 512 with old libc Linux/Aarch64: support SHA acceleration detection with older libc On Linux on aarch64 (64-bit ARMv8) processors, we use getauxval() to detect whether the runtime environment supports SHA-256 or SHA-512 acceleration. Some libc do not define the necessary HWCAP_xxx constants to analyze the result of getauxval(), either because they don't bother or because they're too old to recognize the values we need (for example, HWCAP_SHA2 appeared in Glibc 2.24 and HWCAP_SHA512 appeared in Glibc 2.27). In such cases, assume that the values are the same as in the kernel ABI and define the constants manually.
