The current SVN version currently fails to work on machines that have
strict alignment requirements, for example the SPARC target. This is due
to the way the struct fat_bpb in fs/grubfs/fat.h is defined and accessed
(through FAT_CVT_U16) to avoid padding. Some 16 bits fields like
bytes_per_sect are thus accessed unaligned.
The patch below takes the same approach as for other structures in
openbios, it declares the structure as packed, and lets GCC do the right
things to access those unaligned field.
