Isn't it a design of compat_linux(8) implementation?

So if the dialog box tries to open /usr, it shows /emul/linux/usr,
not real /usr. If there is no /emul/linux/usr/pkg dir it doesn't
show pkg dir on the shadow /usr dialog box, though you could type
"/usr/pkg/bin" directly in the dialog to see real /usr/pkg/bin dir.

If you want to make linux binaries not to search /emul/linux
shadow tree, you could use /../ prefix for file path.
(undocumented but noted in sys/compat/common/compat_util.c)
I.e. if you create a symlink "netbsd@ -> /.." under /emul,
you could see whole NetBSD native tree under /emul/netbsd/
even on any dialog box.
