[linux-pam] Do not use yywrap (ticket #42)

[Dmitry V. Levin]

commit 8da3f3c38e075498a24fb9db80ae9862bda7154d
Author: Dmitry V. Levin <ldv(a)altlinux.org&gt;

    Do not use yywrap (ticket #42)
    
    Our scanners do not really use yywrap.  Explicitly disable yywrap
    so that no references to yywrap will be generated and no LEXLIB
    would be needed.
    
    * conf/pam_conv1/Makefile.am (pam_conv1_LDADD): Remove.
    * conf/pam_conv1/pam_conv_l.l: Enable noyywrap option.
    * doc/specs/Makefile.am (padout_LDADD): Remove.
    * doc/specs/parse_l.l: Enable noyywrap option.
