Repeated attempts to build will fail noisily

[BrianGraysonSiV]

Invoking ./build_all.py --arch native --chip default --board default, and then re-invoking it, will cause it to die with messages like this:

AttributeError: 'NoneType' object has no attribute 'stdout'

The reason is that if all files are up to date, the 'res' object is still None.

A quick fix is to indent the 'res' lines, and the preceding "if not succeeded" lines, as shown here:

diff --git a/build_all.py b/build_all.py
index 8bc38be..2b1263d 100755

-    if not succeeded:
-        log.debug('Command was:')
-        log.debug(arglist_to_str(arglist))
+        if not succeeded:

-    log.debug(res.stdout.decode('utf-8'))
-    log.debug(res.stderr.decode('utf-8'))
+        log.debug(res.stdout.decode('utf-8'))
+        log.debug(res.stderr.decode('utf-8'))

     return succeeded
