+Subject: [PATCH] hostapd: fix space variable and configuration that way
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The hack used to get space variable probably no longer works with newest
+make. This replaces it with version suggested in GNU make documentation.
