As mentioned in the thread discussing the patch errno.h is one of the reasons to require the dirafter, since the tools need the host version of it. A possible solution could perhaps be to place such standard headers in a separate directory and only include it for an u-boot build. The tools can then be compiled without the idirafter and not including this location as an include path.
