This change checks elf_flags for EF_RISCV_RVE and if present uses the RVE linux syscall ABI which uses t0 for the syscall number instead of a7. Warn and exit if a non-RVE ABI binary is run on a cpu with the RVE extension as it is incompatible. Backports relevant parts of 5836c3eccedb6dfab16b8f606f2de24b8938b69c from qemu
