that moderate size increase in start.S breaks nand builds:

Configuring for MPC8313ERDB_NAND_66 board...
start.o:(.got2+0x4): undefined reference to `_GOT_TABLE_'
make[1]: *** [/home/r1aaha/git/u-boot/nand_spl/u-boot-spl] Error 1

...

Configuring for MPC8315ERDB_NAND board...
powerpc-linux-gnu-ld: NAND bootstrap too big

start.o:(.got2+0x4): undefined reference to `_GOT_TABLE_'

(I'm using powerpc-linux-gnu-gcc (Sourcery G++ Lite 4.3-74) 4.3.2 atm).
