configure tests could be disabled without --enable-encryption

[Frédéric L. W. Meunier]

Hi. This is harmless, but the following tests couldn't be disabled by
default and when --enable-encryption isn't given ?

checking for krb.h...
checking for krb_get_err_text... no
checking for GSSAPI
checking for gssapi.h... no
checking for gssapi/gssapi.h... no
checking for krb5.h... no
checking for GSSAPI in /usr/kerberos
checking for gssapi.h... no
checking for gssapi/gssapi.h... no
checking for krb5.h... no
checking for GSSAPI in /usr/cygnus/kerbnet
checking for gssapi.h... no
checking for gssapi/gssapi.h... no
checking for krb5.h... no
checking for GSSAPI... no

I'm using current CVS.
