This problem could be reproduced simply by adding the bootloader module 
into base.pp.

The root cause is that the policy_module() used to require system_r will 
be expanded as EMPTY if the module is built into base.pp (with 
"self_contained_policy" flag set), rendering modules(such as 
bootloader.te) that are copied earlier than kernel.te into base.conf 
found system_r not ever defined or required when referencing it in their 
unconditional block.

The solution is to bump role declarations in the unconditional block of 
base.pp to the top of base.conf, as what has been done for attribute, 
type, alias or boolean declarations. The patch just got posted to the 
mailing list.

Last, it's worthwhile to mention that the bootloader module could be 
properly built as a standalone module without such error, owing to the 
fact that policy_module() could require system_r properly.

Thanks,
Harry
