I spent some time hacking wget to build under the NDK.  It works pretty well, though it's not really in a condition to submit back to mainline.  If you'd like to take a look, though, here's the patch:


To build, get wget from http://ftp.gnu.org/gnu/wget/wget-1.11.4.tar.gz
 and unpack it to android-ndk-1.5_r1/sources/wget.  In the wget directory, run:

./configure --without-ssl --disable-nls --build=arm-eabi

Create android-ndk-1.5_r1/apps/wget/Application.mk:
APP_PROJECT_PATH := $(call my-dir)/project
APP_MODULES      := wget

Change back to android-ndk-1.5_r1 and run:
 make APP=wget V=1

And here's the binary if you want to skip all that trouble:
