I did a git bisect on this and finally reached the end of the line.
Here is what it said:

qpc$ git bisect bad
82ce67bf262b3f47ecb5a0ca31cace8ac72b7c98 is the first bad commit
commit 82ce67bf262b3f47ecb5a0ca31cace8ac72b7c98

    V4L/DVB: staging/lirc: fix non-CONFIG_MODULES build horkage
    
    Fix when CONFIG_MODULES is not enabled:
    
    drivers/staging/lirc/lirc_parallel.c:243: error: implicit declaration of function 'module_refcount'
    drivers/staging/lirc/lirc_it87.c:150: error: implicit declaration of function 'module_refcount'
    drivers/built-in.o: In function `it87_probe':
    lirc_it87.c:(.text+0x4079b0): undefined reference to `init_chrdev'
    lirc_it87.c:(.text+0x4079cc): undefined reference to `drop_chrdev'
    drivers/built-in.o: In function `lirc_it87_exit':
    lirc_it87.c:(.exit.text+0x38a5): undefined reference to `drop_chrdev'
    
    Its a quick hack and untested beyond building, since I don't have the
    hardware, but it should do the trick.
