Thank you for the explanation, Dimitry. As I wrote, I have the host's 
native CPUTYPE in make.conf (CPUTYPE?=core-avx2) and the target on the 
command line (make CPUTYPE=slm buildworld buildkernel).

Since my previous e-mail, I actually had the bright idea of removing 
.../tmp/legacy/usr/bin/install, and that let the installkernel succeed.

My previous assumption that the remainder of the build obeyed the 
override must have been wrong, though, because installworld failed in 
strip for /lib/libc.so.7, and after that, nothing worked anymore.

Perhaps I should get a non-x86(_64) build host and really do a full 
cross build ...

Thanks again,
