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.
