+                    If your build system has the
+                    <filename>oss4-dev</filename> package installed, you
+                    might experience QEMU build failures due to the package
+                    installing its own custom
+                    <filename>/usr/include/linux/soundcard.h</filename> on
+                    the Debian system.
