I'd say yes. The uClibc Config.in help text for this option recommends
to enable it, and it defaults to y, so I think it's pretty safe.

Regarding ARC, I see that there are arch-specific optimized string
functions in libc/string/arc/, written in assembly. So by enabling
GENERIC_OPT, what you gained is that you have optimized versions for
those functions that don't have an ARC-specific assembly implementation?
