Hello,
I successfully compiled buildroot for Raspberry Pi following this guide:

https://github.com/albertd/buildroot-rpi

I had a problem with some applications (btw it was: EGL Error : Could 
not create the egl surface: error = 0x300b) and I read some users were 
able to solve just rebuilding buildroot.
Thus, I issued:

make cleanall

as stated in the documentation. But this time I get the following errors:

Google doesn't help me on this.
Do you have any idea why this happens?

Thanks
Mark
