[Buildroot] Wrong compiling commands ?

[Guillaume Dargaud]

Hello all,
sorry if I ask a lot of newbie questions here, but 12 years since my last 
embedded work on totally different architectures (TI), I have a hard time 
getting back in the game.

The more I look at what is going on, the more I think things are just plain 
wrong. Look at the invocation to compile uClibc:

$ make ARCH=ppc
[...]
/usr/bin/make MAKE="/usr/bin/make -j1" -C 
/home/guinevere/buildroot/toolchain_build_ppc/uClibc-0.9.29 \
        PREFIX= \
        DEVEL_PREFIX=/ \
        RUNTIME_PREFIX=/ \
        HOSTCC="/usr/bin/gcc" \
        all
[...]
Finishing with a whole bunch of errors...
Shouldn't there be a CROSS=something in there ? And some path for PREFIX ?

Thanks
