it would be interesting to have the offending instruction, using
disassemble gdb command (if I remember correctly).
(gdb) disassemble
My guest would be that go generates code for i686 (using some SSE
instruction code for example), and your cpu doesn't have this
instructions (so it complains).

If it is the case, several possibilities:
- your host is too old for using such program, just not do that
- the go compiler should generate i386 code (so no extending instruction
sets) - but does it make sens to try running such program on so old
hardware ? (we already had such discussion about firefox using SSE2 with
Rust on i386. but I dunno if rclone fall in same class than firefox)
Thanks.
