+Subject: [PATCH] build: get rid of sdkdir
+
+Use of sdkdir causes problems during cross-compilation, where the full
+path is then appended to the DESTDIR, leading to host paths being
+appended in the target:
+    https://bugs.busybox.net/show_bug.cgi?id=8696
+
+Other drivers (e.g. keyboard) got rid of sdkdir. Do the same.
