Git rev: master/22c38e2d8a058619e3d05534b5e830b750aa4241


Steps:
1. Download the mips toolchain sdk from above link and install it.
2. Setup environment:
   $ source /opt/poky/1.7/environment-setup-mips32r2-poky-linux
3. Build iptables 1.4.21:
   $ cd iptables-1.4.21/
   $ ./autogen.sh
   $ ./configure ${CONFIGURE_FLAGS}
   $ make

If I skip the step "./autogen.sh", it can be built successfully, but there is a warning message when configure:

This issue only exists for mips toolchain. And it doesn't happen on all distributions. I tested several distributions, it only happened on Ubuntu (14.10/14.04), Debian 7 and CentOS 6. but not happened on Fedora 21, openSUSE 13.2 and CentOS 7

The detail logs are attached.
