[PATCH] dont compile pwd_to_spwd when shadow passwds is off

[Amir Shalem]

hey
this patch disables compliation of pwd_to_spwd when shadow passwords is off
it allows user to compile busybox/uclibc without shadow support.

should it be #ifdef or #if now ?

and should it disable pwd2spwd.c at Makefile.in level ?
