 If you read the thread on cross-compilation that happened about a week
ago, you'll see this is exactly my point ;)
 I was arguing that 1. you need to run executables at build time to
test for system behaviour (even if the d_type thing is a bad example here),
and 2. this is exactly why cross-compilation is difficult, and we need
a global sysdeps database so cross-compilers can fetch the right data
for the target platform.
