can not compile nginx-1.7.6(with epoll supported) with uclibc

[Xia Xiaojin]

hi, all:

i want compile nginx 1.7.6 on my uclibc host with epoll supported,
but the configure export "checking epoll .... found but is not working.'

my host:
root [ nginx-1.7.6 ]# uname -sa
Linux devel 2.6.32-5-686 #1 SMP Sun Sep 23 09:49:36 UTC 2012 i686 GNU/Linux

my target:
libuClibc-0.9.32.so
ucf [ /root ]# uname -sa
Linux ucf 3.14.0-rc7 #5 SMP Tue Aug 5 10:15:00 CST 2014 i686 GNU/Linux
ucf [ /root ]# gzip -dc /proc/config.gz |grep -i epoll
CONFIG_EPOLL=y

vim /data/etc/nginx/nginx.conf
events {

use epoll;
worker_connections 1024;

}
buti will run it :
ucf [ /root ]# /data/etc/init.d/nginx start

Starting nignx: nginx: [emerg] invalid event type "epoll" in /data/etc/nginx/nginx.conf:13

done

Please make sure you are building unmodified nginx. What is, make sure there are no 3rd party patches, including ones to support cross-compilation, and you are building nginx on the target host. If the problem persists, please provide full ./configure output, and the objs/autoconf.err file from the build.

[Maxim Dounin]

Feedback timeout. The problem is believed to be due to 3rd party patches to support cross-compilation.
