What about not using tests which need to run on the target platform :)

It is not always easy, but in numpy cases, it is simple, at least
principle (numscons build does not run any test code, for example):
try_run is used to check whether some preprocessor defined are available
(see numpy/random and numpy/core), which is not necessary. The autobook
specifically mentions that code which need to run on target platforms
should be avoided, since it breaks cross-compilation; with python
distutils, it exactly breaks in those cases.
