New configure option --disable-crypt.
Some Linux distributions are experimenting with a new, separately maintained and hopefully more agile implementation of the crypt API. To facilitate this, add a configure option which disables glibc's embedded libcrypt. When this option is given, libcrypt.* and crypt.h will not be built nor installed.
