Well I just copied it from i386.

i386/i386/machdep.c line 2071+ looks like this:
##################
if (envmode == 1)
	kern_envp = static_env;
else if (bootinfo.bi_envp)
	kern_envp = (caddr_t)bootinfo.bi_envp + KERNBASE;
##################

ia64, i386 and pc98 does it this way and amd64, powerpc and sparc use

kern_envp = MD_FETCH(kmdp, MODINFOMD_ENVP, char *);
