[PATCH] Remove configure check for libcrypt

[Ludovic Courtès]

This patch removes a configure check from 1996, which has been
unnecessary for some time.

OK to apply?

Thanks,
Ludo’.

Subject: [PATCH] build: Remove configure check for libcrypt.

GNU libc has provided the 'crypt' function in libcrypt for a long time,
making this check unnecessary.

* configure.ac: Remove libcrypt check and 'LIBCRYPT' substitution.
* config.make.in (LIBCRYPT): Remove.
* trans/Makefile (password-LDLIBS): Change $(LIBCRYPT) to -lcrypt.
* utils/Makefile (login-LDLIBS, addauth-LDLIBS, setauth-LDLIBS):
  Likewise.
