[Buildroot] uClibc kernel headers problem

I have untared a fresh copy of build root 2009.8. When I run make for
the first time, there is an error regarding the absence of
toolchain_build_arm/uClibc.config.arm and the process stops (see error
log below). If I do 'touch toolchain_build_arm/uClibc.config.arm' then
run make again, there is a series of questions which pertain to which
configs should be used.
I am using my own target/device. But that mainly defines the U-BOOT
config variable (cs-e9302), and I don't have any uClibc configuration
files in that directory. I am just curious if this is a bug or if I am
doing something wrong.
