[U-Boot] Build failures with older toolchain

Hi all,

I pulled u-boot about an hour ago and master is at this commit:

Author: Matthias Weisser <weisserm@arcor.de>
Date: Thu Nov 18 09:35:09 2010 +0100

Makefile: Fix build with USE_PRIVATE_LIBGCC

(plus a small change in omap3_config.h - unrelated)

When trying to build u-boot I was constantly, getting these errors:
arm-none-linux-gnueabi-ld: section .bss [8003f5c8 -> 8007e327] overlaps section .rel.dyn [8003f5c8 -> 80044e57]
arm-none-linux-gnueabi-ld: section .dynsym [80044e58 -> 80044ef7] overlaps section .bss [8003f5c8 -> 8007e327]
arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5c8 overlaps previous sections

Tried to build omap3_beagle and there were no issues; unable to
debug for long, I decided to come back on this problem later.
Opened a new window and started working on my Linux tree.

Returned back to u-boot, and this time build was successful for no
evident change. Took me some time to realise that the toolchain
I was using to work on Linux repo was different - I use an env
script based on activity.

To verify the doubts, I explicitly ran this command with two different
versions of toolchain in my path and I see different results. Here are
last few lines of final build step

The configuration for beagle still build successfully for both toolchain versions.
Any clues/ suggestions? Is there a recent change which hasn't yet been adapted or
ported for omap3evm?

Best regards,
Sanjeev
