Subject: [PATCH 1/1] perf tools: Build x86 32-bit syscall table from
   arch/x86/entry/syscalls/syscall_32.tbl

To remove one more use of the audit libs and address a problem reported
with a recent change where a function isn't available when using the
audit libs method, that should really go away, this being one step in
that direction.

The script used to generate the 64-bit syscall table was already
parametrized to generate for both 64-bit and 32-bit, so just use it and
wire the generated table to the syscalltbl.c routines.

Thanks a lot! Added to the cset.

Oh, 32bit arm still affected:
/usr/lib/gcc/armv7hl-suse-linux-gnueabi/14/../../../../armv7hl-suse-linux-gnueabi/bin/ld: perf-in.o: in function `trace__init_syscalls_bpf_prog_array_maps':
tools/perf/builtin-trace.c:3461:(.text+0x899a0): undefined reference to `syscalltbl__id_at_idx'

Ping -- any input/fix for this?

thanks,
