[Buildroot] built without large file support

[Robert B. Williams]

Am trying to compile grub and it is complaining that large file support 
is turned off and that _FILE_OFFSET_BITS=64.  I guess one of these 
things needs to change....

 From menuconfig I tried to enable large file support in the toolchain 
area....no affect.

Please help...

What do I need to do to boot linux with root filesystem in flash?

So far I created a cpio image and well that runs off of a ramdisk.
