[Buildroot] uClibc kernel headers problem

[Roman Chertov <rchertov@cs.ucsb.edu>]

Hello,

I am using the latest build root release and I am trying to build a tool
chain for CS-e9302 board which has an ARM chip.  I want to use the
2.6.24.7 Linux kernel (I patched it to support click modular router).  I
patched that kernel and u-boot 1.3.3 with patches from
http://dev.ivanov.eu/projects/cs-e9302/ to enable the board support.  I
then renamed the tar.bz2 files into file names that buildroot supports
in the menuconfig (linux-2.6.24.tar.bz2 kernel and
u-boot-2009.06.tar.bz2) and placed the files into the dl directory.

My current trouble is with uClibc 0.9.30.1.  In the buildroot menuconfig
I specified that I want to build the entire Linux kernel, so as far as I
understand there is no need to use the precompiled headers option.  When
I build the tool chain, it all works up to uClibc.  I get the following
error "cc1: error: unrecognized command line option "-mbig-endian"".  I
have included the output log down below.  I would appreciate any help
with this.

Thanks,

Roman
