ELDK-5.5 doesn't behave better. You will always need
CONFIG_USE_PRIVATE_LIBGCC=yes to build all MIPS boards at once and if
you don't have a full multilib toolchain. I'm still wondering why
Wolfgang decided long time ago, that U-Boot should rely on the
toolchain's libgcc and not use its own variant like the kernel does.
