No you shouldn't.

It's dependent on libdl and libc, but ok to strip symbols. I would be
careful when stripping ELF objects because you could be stripping out
unwind information as well (.eh_frame or .debug_frame sections).
Sounds like what you want to do is to get a remote gdb working for
your target, so you can have symbols and get a better handle on where
the binary is crashing. This way you won't be space limited due to
having an embedded target.
