• startup/linkcmds: Removed.
• Makefile.am, start/preload.S, startup/bspstart.c: use linkcmds

from shared area - this version seemed broken anyways. Let the
preloader use the generic 'entry_point_section' rather than its own
'mvme5500_preloader_section'. Also, let zero_bss use (implicit?)
SBSSxxx symbols.
