Alright, cross compilation. Good idea! :-)

I'm trying to understand this myself. I think boost build v2 would
produce lovely win32 executables under linux if a few things change:
every toolset command gets the target platform name prepended to it
(i586-mingw32msvc-gcc) and then it looks like there are only a very few
other things that need to be detected based on the target platform
instead of the build platform. Unfortunately, I don't yet really
understand how to modify boost.build...

Two comments about this <os-api> or <target-os> business: don't forget
sometimes there is no os. Also, autotools uses the --host= argument
which basically specifies the processor and os the compiled program will
run under.
