  Yay! Thanks Eric!

  I don't understand: if you cross-compile, compile-time tests will always
give the wrong results. How do other systems handle cross-compilation, for
instance wrt endianness? There has to be a database of sysdeps somewhere,
that lists the functionalities of various archs. How does Buildroot handle it?
It's certainly possible to make skalibs tap into that database to extract its
own sysdeps; please tell me if I can help.
