[uClibc]Problem with buildroot and own kernel build (missing *.h files)

[Pedro Sanchez]

Hello,

I'm trying to run the latest (from CVS) buildroot using my own kernel
(TARGETS+=linux is enabled in the Makefile). My host system is a PC and
my target is powerpc.

The compilation aborts during the gcc-initial stage because some *.h
files can't be found. In particular it first breaks because of signal.h
(which is of course in the kernel include tree).

I modified linux.mk to redefine DOWNLOAD_LINUX_VERSION and LINUX_VERSION
to match my kernel. Is there something else I have to do? 

Thanks ,
