When we moved to a syscalltbl generated from the kernel syscall tables (arch/..../syscall*.tbl) the idea was to either use it, when having the generator (e.g. tools/perf/arch/x86/entry/syscalls/syscalltbl.sh), or falling back to the previous audit-libs based way of mapping syscall ids to strings and the other way around. At first we just needed the audit_detect_machine() return to then use it to the str->id/id->str, or the other fields for the now used by default in the most well developed arches method of using the syscall table generator. The problem is that then the libaudit code fell into disrepair, and architectures where it is the method used are not working. Now, with NO_SYSCALL_TABLE=1 being possible to pass on the make command line we can automate the testing of that method even on x86-64, arm64, etc. And doing it I noted that we actually use fields in both entries in the union, oops, so ditch the union, as we need all those fields at the same time.
