RAX/RIP are only meaningful for amd64 (and for some stretch i386). If you intent is to only enable this code for amd64 , use #ifdef amd64, not #ifndef.

Can we have small per-arch helpers called there, instead of adding more ifdefs (BTW it should be #ifdef amd64).

Fix ifdefs.

I'd prefer to add the per-arch hooks in a separate commit, together with adding some ARM-specific code, after moving this part into sys/compat/.

What about i386 and linux32 on amd64?

i386 has its own implementation, which I don't intend to touch, apart from moving it so things continue to build (https://reviews.freebsd.org/D32757). We don't support 32-bit Linux ptrace(2) on 64-bit architectures.
