+Subject: [PATCH] Ensure -no-pch is effective
+
+Have configure add a "CONFIG -= precompile_header" to qmodule.pri when
+ -no-pch is specified.  Ensures that Qt is built without precompiled
+headers (as requested) even if allowing precompiled header use is the
+default for the toolchain.
+
+Parallels changes to Windows configure.
+
+Task-number: QTBUG-11545
+Change-Id: Iab4021e74c4e9978770e917dff97b976c449dd8b
+Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@theqtcompany.com>
