Rather than generating individual syscall header files generate a
single trace/beauty/generated/syscalltbl.c. 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.
Add comment for noreturn column suggested by Arnd Bergmann:
