u-boot - Source object has EABI version 5, but target has EABI version 0

When I try to compile u-boot I get the following error:

enter image description here

The error is explained in this link:

http://www.denx.de/wiki/DULG/SourceObjectHasEABIVersion4ButTargetHasEABIVersion0

However, I don't know where to change in the source code.

I changed the line

PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,-mabi=apcs-gnu)

in cpu/arm926ejs/config.mk to

PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,-mabi=aapcs-linux)

This time, I get the following errors:

It seems that the problem relates to libgcc.a.

What I learnt is u-boot compiles with very few compilers.

The link

http://communities.mentor.com/community/cs/archives/arm-gnu/msg02478.html

explains my problem as

This is a simple problem to fix. First you need to understand that the ARM EABI and ARM GNU/Linux toolchains are different. The Linux kernel and applications are compiled with ARM GNU/Linux toolchain, while bootloaders are compiled with ARM EABI toolchain.

U-boot is a bare-metal application, therefore use the ARM EABI toolchain. That is the best way to compile U-boot and other non-Linux applications. It is possible to compile U-boot with Linux toolchain but not recommended.
