The check looks at the config.log.  It is looking for instances where unsafe
compilation or include usage occurs.  In this case it wasn't actually host
includes.. so there is a bug in the error message.  From the config.log:

In the above snippet you'll see 'warning: library search path "/lib" is unsafe
for cross-compilation'.  This indicates that the package passed in a -L/lib, and
the linker caught this and issued a warning.

The fix is to figure out why the configuration file attempted to pass -L/lib,
and stop it from occurring.

Please file a bug on the log message being confusing and I'll attempt to get
that fixed.. (or a patch)  ;)
