Do you also have those (from a working i386 system):
# Linux support
options COMPAT_LINUX # Enable Linux ABI emulation
options LINPROCFS # Enable the linux-like proc filesystemsupport (requires COMPAT_LINUX and PSEUDOFS)
options LINSYSFS # Enable the linux-like sys filesystem support (requires COMPAT_LINUX and PSEUDOFS)
options COMPAT_AOUT # Enable i386 a.out binary support
(note PSEUDOFS is also needed)
No, I haven't added those.
Are these necessary to have
the linux binary compatibility?
The handbook only mentions COMPAT_LINUX.
