I have done exactly this.  There is a way to do it that is presumably 
much easier than using a cross-compiler, because the cross compiler is 
not going to resolve library and dependency issues in the same way.

The solution I used was simply to install as an unpriviledged user. 
This works fine, and the majority of GNU software understands the 
"--prefix=" directive.  I installed (at least) automake, autoconf, glib, 
gtk+, and my own application this way.

For convenience, I used a layout similar to the default.

mkdir ~/usr
mkdir ~/usr/local

export LOCAL_INSTALL=~/usr/local
export LD_LIBRARY_PATH=$LOCAL_INSTALL/lib:$LD_LIBRARY_PATH
export PATH=$LOCAL_INSTALL/bin:$PATH

Then, every time you build and install a library or tool, every 
configure becomes:

./configure --prefix=$LOCAL_INSTALL

You may want to add the 'export' lines to the end of your .bash_login or 
.bashrc file.

Works "auto" magically.  Hail the GNU!  :)

Note: the above may have syntax errors, and is slightly bash-specific
