Do you mean "$PREFIX/aarch64-linux-gnu/include" or
"$PREFIX/include/aarch64-linux-gnu"?
The previous one is a standard location for a cross compiler. The
latter is not enabled without --enable-multiarch, at least for the
upstream GCC code. Note that if you get a GCC source tarball elsewhere,
it's unlikely you may get an answer here because we have no way to know
how the source code is modified.
