Marius Hillenbrand 0dbe61a612 s390x: choose SIMD kernels at run-time based on OS and compiler support ... Extend and simplify the run-time detection for dynamic architecture support for z to check HW_CAP and only use SIMD features if advertised by the OS. While at it, also honor the env variable LD_HWCAP_MASK and do not use the CPU features masked there. Note that we can only use the SIMD features on z13 or newer (i.e., Vector Facility or Vector-Enhancements Facilities) when the operating system supports properly context-switching the vector registers. The OS advertises that support as a bit in the HW_CAP value in the auxiliary vector. While all recent Linux kernels have that support, we should maintain compatibility with older versions that may still be in use.
