[U-Boot] [PATCH] ARM: compiler options cleanup - improve tool chain support

[Gaye Abdoulaye Walsimou]

Dear Wolfgang Denk,
I tested your patch against 7dedefdf749ff02c1086f7ddb8cb83a77b00d030
(latest revision at the moment of writing of u-boot.git).
My toolchain is a home-made toolchain and contains gcc-4.4.1,
binutils-2.19.1, eglibc-2.10.1, kernel headers 2.6.30.4, configured to
generate binaries for arm little endian, eabi, and multilib disable.

Results:
I was unable to compile without the patch in this thread
http://lists.denx.de/pipermail/u-boot/2009-August/058193.html (which is
normal because of gcc-4.4.1).
With 'MAKEALL arm' I have no compile errors except for:
* actux1, actux2, actux3, actux4, ixdp425, ixdpg425, pdnb3, which seem
to be big endian (my toolchain only generates binaries for little endian).
* and "trab board" with this error: armel-unknown-linux-gnueabi-ld:
../../lib_arm/div0.o: No such file: No such file or directory
