I realise I'm being vague. Some explanations below.
In fact, the patch I posted allows one to successfully build a x-compiler
for soft-float armeb (mine is armeb-xscale-linux-uclibc, tuned for Xscale).
Unfortunately, the resulting gcc barfs on the squashfs code in the kernel.
A smaller test-case is available in the bug report, suggesting this is quite
easy to hit.
That's why I've reverted to gcc-4.0.4, which still needs the attached patch,
but Just Work (TM).
Regards,
Yann E. MORIN.
