I'd say it depends the $(@D) of which step. Indeed, in the (admittedly
long term) perspective of per-package out-of-tree build, the source
tree would be shared between the host and target builds of a given
package, and this cross-compilation.conf file would only make sense for
the target variant of the package, and therefore it should be in the
build directory of the target variant.

So, if this file is generated during the "configure" step, we are good,
because $(@D) will point to the build directory. If it's generated in
an earlier step, $(@D) points to the source directory (with per-package
out-of-tree build implemented, of course).

Best regards,

Thomas
