This patch fixes the linker problems noticed while building the omap3_evm with Codesourcery toolchains 2009q1, 2009q3 and 2010q1.
The compilation was tested as success for both omap3_evm and omap3_beagle with toolchain versions 2009q1 and 2010q1.

The patch touches all ARMv7 architectures, will need to be reviewed thoroughly.
I am getting hang of relocation feature, but definitely hands-on. Impact would have to be reviewd as well. This is the reason for sending the patch early - before i start testing on the evm.

The u-boot built after this change alone gets stuck somewhere after dram_init(). However, removing the "sort" from LIBS (as suggested by Wolfgang), the u-boot comes up fine on the omap3_evm.
