Just in case, this is what I get with my busybox (v1.24.1):

# wc --max-line-length
wc: unrecognized option '--max-line-length'
BusyBox v1.24.1 (2018-02-10 17:35:25 CET) multi-call binary.

Usage: wc [-clwL] [FILE]...

I looked very quickly and it seems to be glibc with "getopt" function
that prints this error:
https://sourceware.org/git/?p=glibc.git;a=blob;f=posix/getopt.c#l309
