[Buildroot] [PATCH 1/1] packages/linux-pam: bump version to 1.1.8 -> 1.2.1

[Carlos Santos]

> Move to the latest release of linux-pam. This allows us to remove
> a number of patches and consolidate the existing ones :
> 
> - 0001-configure.patch
> - 0007-rhosts.patch
> 
> these two patches deal with the ruserok function, which is not
> usable with uclibc. Consolidated into
> 0002-Conditionally-compile-per-ruserok-availability.patch.
> 
> - 0003-group.patch
> - 0005-succeed.patch
> - 0006-time.patch
> 
> these three patches deal with the innetgr function, which is not
> usable with uclibc. Consolidated into
> 0003-Conditionally-compile-per-innetgr-availability.patch.
> 
> - 0004-mkdir.patch
> 
> Fixed in upstream, no longer required.
> 
> - 0002-doc-makefile-am.patch
> 
> renamed to 0001-doc-makefile-am.patch.
> 
> - 0008-fix-CVE-2014-2583.patch
> - 0009-fix-CVE-2013-7041.patch
> 
> These patches are already included in the new release and so
> can be safely deleted.

BR2_PACKAGE_LIBFFI=y
BR2_PACKAGE_LINUX_PAM=y

BR2_PACKAGE_LIBPAM_TACPLUS=y

Built linux-pam-1.2.1, libpam-tacplus-1.3.9 and libpam-radius-auth-1.4.0.

Did not perform a run-time test, since it would require a network setup with
TACACS+ and RADIUS servers.
