That didn't go very well..

% pwd
/data/qemu/qemu_cvs/arm-user
% cat x.c
#include <stdio.h>
#include <stdlib.h>
 
int main()
{
        return 0;
}
% armv5b-softfloat-linux-gcc -Wall -o x x.c -static
% file x
x: ELF 32-bit MSB executable, ARM, version 1 (ARM), for GNU/Linux 2.4.3, 
statically linked, not stripped
% tail -1 config.h
#define TARGET_WORDS_BIGENDIAN 1
% ./qemu-arm ./x
qemu: uncaught target signal 11 (Segmentation fault) - exiting
