In a syscalltbls array have references to each architectures tables along with the corresponding e_machine. When the 32-bit or 64-bit table is ambiguous, match the perf binary's type. For ARM32 don't use the arm64 32-bit table which is smaller. EM_NONE is present for is no machine matches. Conditionally compile the tables, only having the appropriate 32 and 64-bit table. If ALL_SYSCALLTBL is defined all tables can be compiled.
