I had same problem with u-boot compilation on eldk-5.4, and did this
to work around it. You can probably do something similar...

--- a/Makefile
+++ b/Makefile

 endif
 PLATFORM_LIBS += $(PLATFORM_LIBGCC)
 export PLATFORM_LIBS

My build script is:

#!/bin/bash
eval ` eldk-switch.sh -m -r 5.4 armv7a`
#make mrproper wagabuibui_config
#make mrproper socfpga_cyclone5_config
nice make -j 3 u-boot.img && \
cp u-boot.bin /srv/tftp

(I assumed something was wrong with my setup, so I did not investigate
further.)
