Can't do what? Directly use sysctlbyname?
How about:
/*
* This syscall was created to make sysctlbyname(3) more efficient, but
* we can't really provide it in bsd-user. Notably, we must always translate
* the names independently since some sysctl values have to be faked
* for the target environment, so it still has to break down to two syscalls
* for the underlying implementation.
