I don't understand this error message... It seems like a linker error, but it
also seems to refer to an incorrect include file? Is this during linking or
compiling?

What do you mean, exactly? In r230622 I explicitly set the PATH to
${BPATH}:${PATH}, which should be enough to pick up the bootstrap tools. This
is exactly the same path used to build the bootstrap-tools stage itself. The
kernel bootstrap tools (only aicasm, really) should be built by the host
compiler, not the cross-tools compiler.

I don't think this is correct, as aicasm should be compiled by the host
compiler, and linked with the host libc. So if you start including headers
from the source directory, there will be a mismatch between what those headers
declare, and what is available in the host libc.
