It looks like Busybox PAM support depends on the PAM library, for which
we don't have a package yet.

So you would need to :

 * Create a Buildroot package for
   ftp://ftp.kernel.org/pub/linux/libs/pam/library/Linux-PAM-1.1.3.tar.bz2

 * Create a sub-option in the Busybox Buildroot package to
   enable/disable PAM support. This option should select the PAM
   library package created at the previous step.

 * In package/busybox/busybox.mk, if PAM support is enabled, then tweak
   the Busybox configuration file, and add the dependencies on the PAM
   library.

Regards,

Thomas
