Recent alsa upgrade stripped /usr/include/alsa directory from include path reported by pkgconfig. Due to this pulseaudio 12.2 configure script can find alsa's use-case.h header which in turn results in HAVE_ALSA_UCM being undefined. This turn results in pa_alsa_ucm_device_update_available symbol missing even though libalsa-util.so needs it. Once could argue pulseaudio should not allow undefined symmbols in its shared modules. Unfortunately it does and due to this current OE builds of pulseaudio crash when the server tries to dlopen any module using libalsa-util.so. Fix this by backporting ustream alsa header include fix.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
