* configure (main): Copy <srcdest>include/<kernel>/<arch>/*.h to
include/.
* configure.sh: Likewise.
* .gitignore: Ignore them.  Add copyright header.
* build-aux/bootstrap.sh.in (AM_CPPFLAGS): Replace
<srcdest>include/<kernel>/<cpu> with built ../include.
* build-aux/build.sh.in (AM_CPPFLAGS): Likewise.
* build-aux/install.sh.in: Also install built include.
