default. Keeping the feature enabled is safe. Disabling it permits
to disable the references to the SHA256 and SHA512 password
encryption algorithms from the usage help and manuals (in addition
to the support for these algorithms in the code).
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
src/chpasswd.c, src/chgpasswd.c, src/passwd.c: ENCRYPT_METHOD is
always supported in login.defs. Remove the ENCRYPTMETHOD_SELECT
preprocessor condition.
* libmisc/obscure.c, libmisc/salt.c, src/newusers.c,
src/chpasswd.c, src/chgpasswd.c, src/passwd.c: Disable SHA256 and
SHA512 if USE_SHA_CRYPT is not defined (this corresponds to a
subset of the ENCRYPTMETHOD_SELECT sections).
