IPX is marked obsolete for serveral years. so remove it and the
dependency in linux tree.
I'm sorry to not thinking about linux-audit and strace.
Might you remove the dependency or make the part of the code.
Many thanks.

Unfortunately, that is not how UAPI works.  That change breaks
building
of the existing code;  one cannot change already released versions
of either audit, strace, or any other userspace program that happens
to unconditionally include <linux/ipx.h> without any fallback (like
<netipx/ipx.h> provided by glibc).

Also, the <netipx/ipx.h> fallback is only provided by glibc (and maybe
uclibc?). With this patch, it is now impossible to compile even the
very latest version of "strace" with a musl toolchain.

I've made support for ipx optional in audit user space a couple weeks back. 
It's no longer a problem for us.
