Arnaldo Carvalho de Melo 0e7eb23668 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.
