This adds the special .NOTPARALLEL target to include/Makefile when
building on darwin, to work around an apparent bug in the APFS
filesystem.

* configure.ac (INCLUDE_DIR_NOTPARALLEL): Define.
* configure: Regenerate.
* include/Makefile.am (INCLUDE_DIR_NOTPARALLEL): Add .NOTPARALLEL when
defined.
* include/Makefile.in: Regenerate.
Tested powerpc64le-linux, and FX reports it works on Darwin. I'll
backport this to the active branches too.
