# @FUNCTION: copy_system_binaries
# @USAGE: <DESTDIR> <system binaries to copy>
# @DESCRIPTION:
# Copies system binaries into dest dir.
#
# Difference to copy_binaries() is, that copy_system_binaries() does NOT
# try to recreate directory structure. Any system binary to copy will be
# placed into same DESTination DIRectory.
# Because we focus on *system* binaries, it's safe to assume that everything
# belongs to the same directory. This assumption will allow us to copy from
# crossdev environments (i.e. /usr/$CHOST).
