[uClibc] xscale/soft-float compilation fails

[maryam]

Using buildroot/uclibc/busybox 1.0, I'm trying 
to cross-compile my tools and libraries for a
ixp2800/xscale plaform. Using "make menuconfig",
from "Toolchain Options", if I didn't select  
"Use software floating point by default", then
compilation goes well, but if I did select it then
I get the following error:

gcc -c  -DUSE_UCLIBC -g -O2 -DIN_GCC -DCROSS_COMPILE

Since xscale doesn't have HW floating point support,
I figured I have to build my tools for soft-float.
Also, the whole thing started when I couldn't get
my /bin/sh started when I try to login. I traced the
problem to setjmp() instruction in shell/ash.c file
where system crashed trying to execute it.
Does anybody know what I'm doing wrong or has any
suggestions to get around this problem?

Thanks,
Maryam
