oe-run-native: print more error messages

Fixed:
$ bitbake bmap-tools-native -ccleansstate && bitbake bmap-tools-native && oe-run-native bmap-tools-native bmaptool --help
[snip]
Error: Unable to find '' in <PATH>
[snip]

Note the blank '' word, it was because "tools" was overrided, now fix it.

And also check whether the recipe is a native one or not.
