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.
