I don't know the MIPS ABI.  If it doesn't require alignment for the
char d_name[256] member, surely we can do the conversion inline, just
by calling memmove on the name?  d_ino, d_off, d_reclen already have the
right size.

The present code already assumes that the d_type member is always
present at the end of the record, so there is always enough space, I
think.

Thanks,
