If I understand your question correctly:
grub-install --directory=/path/to/grub/on/USB/<arch> ...
e.g.
grub-install --directory=/mnt/usb/usr/lib/grub/i386-pc ...
Not everything is really possible to cross-platform. In particular, any
actions that involve updating system NVRAM are obviously not possible
unless you are on this system.
You may also look at grub-mkrescue which creates bootable hybrid
ISO/USB image for all platforms present in /usr/lib/grub/<platform> (or
where it is installed).
