open snoop for 32 bit apps on 64 bit platforms

I want to extend opensnoop to capture 'open' syscalls from 32 bit applications running on a Linux 4.18 x86_64 system. If I use bpftrace with tracepoint:raw_syscalls:sys_enter, I don't see any relevant 32 bit compatible syscalls being picked up for the applications. Does BCC support 32 bit compatibility mode, and if so, are there examples or documentation available on how to capture these calls?

Start by reading the opensnoop implementation and the BCC handling for raw_syscalls on Linux x86_64, then reproduce the missing 32-bit syscall captures described in the issue. Determine whether compatibility mode is supported and identify the examples or documentation needed; done means the behavior and usage are clearly established.
