+klcc-cross: Add patch to use /usr/bin/env perl
+Certain configurations (such as autobuilders) may build in very
+deep paths (that are longer than the #! mechanism allows) which
+makes it unsafe to use the direct path for perl.  In our case we know
+that /usr/bin/env perl will always return ours (if it has been built).
