FreeBSD/ARM just switched from GCC to Clang, which is
why this just got noticed.  U-Boot is used quite heavily for
FreeBSD/ARM (and MIPS and PowerPC as well, I believe).

Here are the options I see for getting
   cc -print-file-name=include
to work again:

  * Hack clang to handle -print-file-name=include specially.
    I did this for GCC already, but I'm not thrilled about it.

  * Configure clang differently so that this option works.

  * Symlink /usr/include to appear somewhere that clang expects.

  * Rearrange our directory layout slightly to match clang's expectations.
