I have successfully compiled libiconv package on my OpenWRT SVN (r11785) source tree; however, I noticed the library as well as the include files are installed under $(STAGING_DIR)/usr/lib/libiconv directory as shown below:

[mazilo@Mi:/opt/tmp/openwrt-svn-trunk 493%] ~ dir staging_dir/mipsel/usr/lib/libiconv/lib

The following excerpt of the OpenWRT Makefile for libiconv package is responsible to install the library and include files on to the $(STAGING_DIR)/usr/lib/libiconv directory:

define Build/InstallDev
        mkdir -p $(1)/usr/lib/libiconv/include
        $(CP) $(PKG_INSTALL_DIR)/usr/include/iconv.h $(1)/usr/lib/libiconv/include/
        mkdir -p $(1)/usr/lib/libiconv/lib
        $(CP) $(PKG_INSTALL_DIR)/usr/lib/libiconv.{a,so*} $(1)/usr/lib/libiconv/lib/
endef

Can anyone please comment why the library and include files are not installed in $(STAGING_DIR)/usr/lib and $(STAGING_DIR)/usr/include directories, respectively?
