According to the crosstool documentation at www.kegel.com:

I could successfully build u-boot 1.1.1 and 1.1.4 for ATMEL at91rm9200 CPU with softfloat option using following Kegel combination: gcc-3.4.5-glibc-2.3.6/arm-softfloat-linux-gnu (linux kernel and root file systems are also built and working).
However I could run only u-boot 1.1.1 and that only after change:
==== //depot/L150/uboot/u-boot-1.1.1/include/asm-arm/global_data.h#2 (text) 63a64
#ifdef GD_PTR_IN_REGISTER
64a66,68
#else #define DECLARE_GLOBAL_DATA_PTR extern volatile gd_t *gd #endif
==== //depot/L150/uboot/u-boot-1.1.1/lib_arm/board.c#3 (text) ==== 39a40
volatile gd_t *gd;
Basically, I don't put gd into the register - crosstool somehow doesn't compile it properly (I examined the assembler).
