Actually, I am not sure this is the best fix we could do. Having the C
library installed in /usr/lib in the sysroot is a bit weird, and I
believe we should rather fix the Buildroot musl package to ensure that
the C library gets installed in /lib instead.

Do you want to have a look into this?

Thanks!
