[U-Boot] [PATCH] ARMv7: Fix linker errors across toolchain versions

[Sanjeev Premi]

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.
