[Buildroot] Kernel sources supplied from my PC

[Martin Peevski <martin@ronetix.at>]

Hello, I want to ask you how can I supply some of the needed sources for 
building Linux system from my PC? This is because sometimes I haven't 
server with some custom Kernel version, for example, and have only my PC.

I search in the manual and there have section "Offline builds" but it 
can't help me, I think? When I execute make source the needed sources 
will be downloaded from internet again?

I think that I can copy my sources to /dl directory of Buildroot but 
when execute make distclean it dissapear. Or I must create it manualy 
and then copy my sources there?

Thanks in advance!
Martin.
