In fact, your commit does much more than fixing the sam-ba symlink
depending on the host architecture: the sam-ba symlink was *always*
broken. Indeed, you're changing this:

-	ln -sf ../../opt/sam-ba/sam-ba $(HOST_DIR)/bin/sam-ba
+	ln -sf ../opt/sam-ba/$(SAM_BA_BIN_NAME) $(HOST_DIR)/bin/sam-ba

I.e you're removing one level of ../ when creating the relative
symlink. And this is needed since we moved $(HOST_DIR)/usr to
$(HOST_DIR).

So even on a x86 32 bit system, where the binary is named "sam-ba",
your commit fixes the symbolic link. I've reworded the commit log
accordingly, and applied your patch. Thanks!

Peter: this commit qualifies for 2018.02.x.

Joshua: what about updating to 2.17, or even Sam-ba 3.x ?

Best regards,

Thomas
