Hello, could someone lend me a hand?

I am using buildroot 3.0.0 and the following occurs:

~/buildroot-avr32-v3.0.0/output/build/linux-2.6.35.4$ make ARCH=avr32 CROSS_COMPILE=avr32-linux-

Firstly, am I working in the right directory: output/build/linux-2.6.35.4
?

Where can I find info about this stuff, because in the buildroot site at documentation there seems to be none :/

And about these 3/27 section mismatches, should I do something about them?

Thanks :)
