Are you building in /usr/src, or are your sources located some place else?

Really need the log that includes the cc command line, as that has the
tell tell -I/usr/src/sys in it.  That component is totally bogus!  At
no time should a src tree rooted at /usr/src-topo be trying to use files
from /usr/src/.

It could be, but more info would be needed.

In my case I was able to proove it out as my compile from /usr/src-topo
worked just fine after I copied my 3 modified header files to /usr/src.
