Subject: [PATCH] Fixed incorrect LLONG alignment for openrisc and cris
OpenRISC (or1k) has long long alignment to 4 bytes, but currently not
defined in abitypes.h. This lead to incorrect packing of /epoll_event/
structure and eventually infinite loop while waiting for file
descriptor[s] event[s].
Fixed also CRIS alignments (1 byte for all types).
