PR 1786/bsps
* Makefile.am: Add support for Altivec.
* startup/bspstart.c, Makefile.am: Use shared/startup/zerobss.c instead.
* make/custom/mvme5500.cfg: Change CPU_CFLAGS to
"-mcpu=7450 -mtune=7450 -Dmpc7455"
* irq/BSP_irq.c, pci/detect_host_bridge.c, pci.c, pcifinddevice.c:
Remove warnings.
* vme/VMEConfig.h, include/bsp.h: use VME shared IRQ handlers.
* network/if_100MHz/GT64260eth.c: Recycle the Rx mbuf if there
is any Rx error.
