Subject: Makefile: don't cross-compile executor if cross-compiler is missing

We started building netbsd executor on linux.
This fails on CI since cross-compiler is missing.
But we don't want to exclude netbsd from presubmit entirely.
So check if cross-compiler is missing and just produce a warning.
This should unbreak CI and humans will see the warning.
