eWobbuh, be aware though that many popular free software packages (even 
autotooled ones) will not successfully cross-compile without extensive 
patching.  There are a lot of package maintainers out there who don't 
care about cross-compilation, or don't know how to use autotools to 
allow for it (abuse of AC_TRY_RUN, for example, is widespread).

You would also be well advised to look at using a build system such as 
openembedded if you want to cross-compile standard free software 
packages without hitches.  Even if you don't use oe to do your 
cross-compilation, its package metadata is a good guide to the gotchas 
associated with cross-compiling any particular package, and it includes 
patches that you are likely to need.
