Collect implementation internal read-only flags in odp_global_data_ro_t into a bitfield. Signed-off-by: Matias Elo <matias.elo@nokia.com>
Arm FEAT_RNG is optional and depending compiler flags __ARM_FEATURE_RNG may be defined even though the feat is not available on the particular CPU. For example, on NVIDIA Grace with '-mcpu=neoverse-v2' __ARM_FEATURE_RNG is defined which currently leads to an illegal instruction failure. Fix the issue by detecting FEAT_RNG support at runtime.
