The reason for this is that OpenWRT doesn't depend much on what the 
system has installed at all. Instead, the canonical way that it, and 
other similar systems like OpenEmbedded, does things in situations such 
as this is to build package X once in "host" mode, for installation into 
a staging directory, and then to use the "host" build of X to help build 
the "target" build of X. So it's important to be able to tell the guest 
build to use a particular instance of racket for bootstrapping, just as 
it is important to be able to tell it which C compiler to use.

Excellent - as you say, these are likely to be good starting points for 
experimentation. I'll have a look at the code to get a feel for what the 
others do, as well.
