Some architectures like AArch64 may not have the open syscall because it was superseded by the openat syscall, so check and use SYS_openat if SYS_open is not available. Additionally, Android headers for AArch64 define SYS_open to __NR_open, even though __NR_open is undefined. Undefine SYS_open in that case so SYS_openat is used.
