Our Air Quality f9ae521710 newlib: rebuild with the global stdio streams enabled.
This change means that there is only one set of global stdin, stdout, and stderr
FILE streams shared by all the threads. This reduces memory usage and avoids
having to close these streams before threads exit. These streams still have a
lock to synchronise access.
