[m-rev.] diff: avoid reconfiguration of libatomic_ops

[Julien Fischer]

Branches: main

scripts/prepare_install_dir.in:
 	Attempt to preserve file attributes in the boehm_gc/libatomic_ops
 	directories.  This can prevent autoconf needing to re-invoked.

 	Use "cp -R" rather than "cp -r".  The latter is not as portable.

Julien.
