[PATCH v5 13/18] riscv: Add RVV strlen for multiarch and non-multiarch

[Andreas Schwab]

This breaks statically linked programs when any tunable env var is set,
because __tunables_init calls strlen, which jumps to the uninitialized
PLT.

$ echo 'int main() { return 0; }' > main.c
$ gcc -static main.c -o main
$ MALLOC_CHECK_=3 ./main
