Use "the most universal file system" which isn't even a
file system: tar.

First, create a tar archive (not a _file_!) to the USB
media as if it was a tape. On the sparc machine:

	# tar cvf /dev/da0 <your stuff>

You can add compression flags like z and j if you need.
To list what you've got, use "tar t" accordingly.

Then uncompress directly from the media on the non-sparc

	# tar xvf /dev/da0

See "man tar" for other options you might want to add.
Also note that in this case, no file system is involved,
so you can't mount anything here.

That's true. Don't you have any floppies at hand? ;-)

(Note: The tar approach also works on floppies, and even
across OS borders, e. g. between Solaris and Linux.)
