commit 670a1ff8f97962efd6b27436b50fc51b62683c25

    Fix password checking with as-needed linking
    
    Newer gcc toolchains tend to enable as-needed by default, so runtime
    detection of libcrypt will fail.  We can just explicitly link against
    libcrypt anyway.
    
    * configure.ac: Check for `crypt()' in libcrypt.
    * config.make.in: Substitute HAVE_LIBCRYPT.
    * libshouldbeinlibc/idvec-verify.c: Include <crypt.h> only when libcrypt
    is available.  Replace weak reference with explicit call and fallback
    macro.
    * utils/x.c: Likewise.
    * libshouldbeinlibc/Makefile (LDLIBS): Add -lcrypt when libcrypt is
    available.
