Subject: [PATCH] shairport-sync: fix cross compilation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Tools from the glib.dev output need to be in PATH for cross
  compilation to work. Not sure if there is a cleaner way than my string
  trick to do it…

- The upstream configure script neglects to check for $AR properly, so
  we need to pass it explicitly.
