polish testing a bit further

build

@@ -73,6 +73,36 @@ This is equivalent to:
 ....
 ./%(prog)s --arch x86_64 qemu-buildroot
 ....
+
+Another important target is `all`:
+
+....
+./%(prog)s all
+....
+
+This does not trully build ALL configurations: that would be impractical.
+But more precisely: build the reference configuration of each major component.
+
+So e.g.: one config of Linux kenrel, Buildroot, gem5 and qemu.
+Don't do for example all possible gem5 configs: debug, opt and fast,
+as that would be huge. This ensures that every piece of software
+builds in at least one config.
+
+TODO looping over emulators is not currently supported by this script, e.g.:
+
+....
+./%(prog)s --arch x86_64 --arch aarch64 all
+....
+
+Instead, for the targets that are emulator dependent, you must select the
+taret version for the desired emulatore, e.g.:
+
+....
+./build --arch aarch64 baremetal-qemu baremetal-gem5
+....
+
+The reason is that some targets depend on emulator, while others don't,
+so looping over all of them would waste time.
