I think (seem to recall something on the list) there have been
multiple people reporting the make O= option doesn't work with
CONFIG_FIRMWARE_IN_KERNEL,

That shouldn't be the case -- it works fine here.

Andrey, what version of make are you using? Does it give you any clues
if you use 'make V=1' or 'make -d firmware/built-in.o' ?  

 but what does the CONFIG_PREVENT_FIRMWARE_BUILD=y option do?  If it
does what it appears to by its title, looks like you might need to set
that to =n

Nah, that's something entirely different. That's for GPL-compatible
firmware where we actually _have_ the source in the kernel tree too, but
the user probably doesn't have the required tools so we don't usually
bother rebuilding it.
