ok: fix this by modifying the cross compiler usr/include/sched.h,

my desktop with linux header version 2.6.19.2 also have this problem..
after fixing this, ether_wakup seems refuse to build with uClibc(snapshot
version)

I use `readelf -s' to find symbol `ether_hostton, it doesn't exist, however,
it's availiable in glibc.
after I un-select CONFIG_ETHER_WAKEUP, I still get the following problem:

I think maybe the 2.6.19.2 linux header is not a prefered version to build
busybox.. any ideas? thanks!
