Ah, sorry, I used the autotools vocabulary you may not be familiar with:
when cross compiling, you have at least two platforms, build and
host/target (host/target is the same unless you build cross-compilers).
If I build foobar on linux for windows, linux is the build, windows the
host/target.

Anything which runs on the host/target platform cannot work in this
context; anything on the build of course can - which generally includes
compilers, etc... Basically, assuming a working compiler,
pre-processing, compiling, linking test code snippets is OK. Running is not.

cheers,

David
