+Subject: [PATCH 4/6] Set arm_tune to empty string if mtune flag is not set by
+ toolchain
+
+Since the default arm_tune option applied by chromium is not
+recognized by our gcc toolchain set arm_tune to empty string
+to prevent chromium from setting a default. Our toolchains
+set the arm version which already implies the corresponding
+mtune option anyway.

+
+This fixes cross-compile settings detection for cross-compilation
+environments where the C compiler cross-compilation flags are set in
+CC/QMAKE_CC instead of CFLAGS/QMAKE_CFLAGS (e.g. OpenEmbedded).
