Error while cross-compiling PHP 5.2.1

[Colin Dean <cdean@xxxxxxxxxxxxxxxxxx>]

Greets,

I'm a new subscriber, so I hope that I've targeted the correct list for 
this issue.

I'm attempting to cross-compile PHP on x86 for 386. I'm using uClibc and 
gcc4.

Here's the error I'm getting:

[root /mnt/vj/sources/php-5.2.1]# make
/bin/sh /mnt/vj/sources/php-5.2.1/libtool --silent --preserve-dup-deps 
--mode=compile i486-pc-linux-uclibc-gcc  -Iext/reflection/

My configure command:
./configure \
--prefix=/mnt/vj/usr --sysconfdir=/mnt/vj/etc \
--disable-all \
--with-flatfile \
--with-config-file-path=/etc/php \

I'll need to later add the necessary things to run nanoweb, but I want 
to try to get a base php install working first.

Any ideas what may be causing this? Something tells me it might have 
something to do with uClibc, but this post 
https://www.geexbox.org/sympa/arc/devel/2006-11/msg00031.html seems to 
think otherwise. I've also brought this problem to the attention of 
clfs-support, but couldn't resolve it 
(http://www.mail-archive.com/clfs-support@xxxxxxxxxxxxxxxxxxx/msg00643.html).

Thanks for your help.
