netwinder: fix base, minimize kern.ldscript diff with evbarm 

New binutils align to 0x10000, not 0x8000 (which makes sense), so
adjust the base to be 0x10000 so that we are loaded at a page boundary
and (I guess) don't smash the firmware in the first page.  While here,
sync with ldscript.evbarm.

Makes my netwinder boot again.
