[U-Boot] current head don;t compile for mpc52xx based boards

[Heiko Schocher <hs@denx.de>]

Hello,

actual head doesn;t longer compile for the mpc52xx based
digsy_mtc_rev5 board (and a fast check, it seems it is
for mp52xx, 8xx, ppc4xx based boards):

[hs at pollux u-boot]$ ./MAKEALL digsy_mtc_rev5
Configuring for digsy_mtc_rev5 - Board: digsy_mtc, Options: DIGSY_REV5
libstubs.o: In function `app_startup':
/home/hs/charon/u-boot/examples/standalone/stubs.c:197: undefined reference to `__bss_end__'
/home/hs/charon/u-boot/examples/standalone/stubs.c:197: undefined reference to `__bss_end__'
make[1]: *** [hello_world] Fehler 1
make: *** [examples/standalone] Fehler 2
make: *** Warte auf noch nicht beendete Prozesse...
ppc_6xx-size: './u-boot': No such file

--------------------- SUMMARY ----------------------------

Boards with warnings or errors: 1 ( digsy_mtc_rev5 )

    rename _end to __bss_end__

    Currently, _end is used for end of BSS section.  We want _end to mean
    end of u-boot image, so we rename _end to __bss_end__ first.

If I find time, I look in it, but if somebody has an idea,
it would be great!
