FYI, below are the 7 fixes in this area that i've queued up so far. Let

Subject: drivers/media build fix for modular builds
From: Ingo Molnar <mingo@...e.hu>
Date: Wed Apr 30 09:36:42 CEST 2008
fix build bug:
LD kernel/built-in.o
LD drivers/built-in.o
ld: drivers/media/built-in.o: No such file: No such file or directory
which happens if all media drivers are modular:
http://redhat.com/~mingo/misc/config-Wed_Apr_30_09_24_48_CEST_2008.bad
In that case there's no obj-y rule connecting all the built-in.o files and
the link tree breaks.
the fix is to add a guaranteed obj-y rule for the core vmlinux to build.
(which results in an empty object file if all media drivers are modular)

IMO, it's the reverse selection from sound to V4L that makes things
complicated. I believe it's better to fix it as a normal dependency.
How about the patch below?
Takashi
Fix kconfig dependency mess of fm801-tea575x
FM801-tea575x tuner has a reverse selection to V4L1 and this causes
dependency problem. The patch simplifies the dependency with a
normal depend on VIDEO_V4L1.

x86.git randconfig testing found the following build error:
drivers/built-in.o: In function `v4l2_i2c_drv_attach_legacy':
tuner-core.c:(.text+0x1a829d): undefined reference to `v4l2_i2c_attach'
drivers/built-in.o: In function `tuner_command':
tuner-core.c:(.text+0x1a971c): undefined reference to `v4l_printk_ioctl'
the reason is that the TEA5761/TEA5767 tuner code is dependent on
(legacy?) V4L infrastructure like v4l2_i2c_attach, by virtue of
drivers/media/video/tuner-core.c including media/v4l2-i2c-drv-legacy.h
and ./sound/i2c/other/Makefile doing:
snd-tea575x-tuner-objs := tea575x-tuner.o
for now i solved this via adding a VIDEO_V4L2_COMMON dependency
to MEDIA_TUNER - but i suspect there might be a better fix as well.
