Normally one does not examine the whole build infrastructure
to determine if a specific item might not be used at some
stage for a specific target. Instead one just supplies the
items for each make command. So, more like:

make DESTDIR=/mnt/usb/i386 TARGET_ARCH=arm64 installworld

I'll note that naming conventions look odd in the above:
Why would /mnt/usb/i386 be the name of a directory that
will contain files for arm64 instead of for i386? The naming
looks likely to be misleading/confusing.

Less of an issue is /mnt/usb : Presuming "mount . . . /mnt"
was used, having a directory called usb inside the file
system mounted is unusual. It would be even more unusual
to have added a usb directory below /mnt and to have used
"mount . . . /mnt/usb". Creating /media/usb and using
"mount . . . /media/usb" would be more like what is
typical. Normally /mnt is an empty directory before (and
after) it is used as a mount point but /media is not
empty because it contains empty directories used as
mount points.
