The source tree is fine. It's just not configured. The actual
configurations for all kernels are in separate directories [1]. For
plain kernel Makefiles that's transparent. lirc's configure magic
tries to be smart but fails to detect that setup though. I never
bothered trying to understand or fix that magic as it's not useful
for building rpm packages anyways. For the lirc kernel module rpm
packages I basically drop a custom Makefile into every driver
directory and call make for every kernel flavor SUSE ships (pae,
smp, xen etc). Manually that would look like this:

/tmp/lirc/drivers/lirc_dev $ cat Makefile
EXTRA_CFLAGS    := -I$(src)/../..               \
        -DLIRC_MAJOR=61         \
        -DIRCTL_DEV_MAJOR=61    \
        -DDEV_LIRC='"lirc"'     \
        -I$(srctree)/drivers/media/video

lirc_src = $(wildcard $(src)/*.c)
obj-m := $(lirc_src:$(src)%.c=%.o)

/tmp/lirc/drivers/lirc_dev $ make -C /lib/modules/`uname -r`/build M=$(pwd) modules
