build kernel with o=<outside tree build failes issue 3.0.8

[rodb70]

When trying to build Linux kernel by placing kernel object files outside tree the build fails with following error message:
CC drivers/video/jz4780-hdmi/api/api.o
Assembler messages:
Fatal error: can't create drivers/video/jz4780-hdmi/api/api.o: No such file or directory
make[6]: *** [drivers/video/jz4780-hdmi/api/api.o] Error 2

Command to replicate issue:
make ARCH=mips CROSS_COMPILE=mips-linux-gnu- uImage O=../build/kernel/

Workaround to continue building:
mkdir -p ../build/kernel/drivers/video/jz4780-hdmi/{api,bsp,core,edid,hdcp,phy,test,util}
