description:
The bytes_transfer_piod_read_auxv test uses 4096 for the size param
to bytes_transfer() which asserted that the size is < the size of 512 AuxInfo
structs.   On a 32 bit system, an AuxInfo is 8 bytes, and 512 AuxInfo
structs is thus 4096 bytes, and 4096 is not < 4096, so the assertion
failed.   It would probably work as a <= assert, but I am not confident
enough with this test case to make that call, so instead increase the
array size to be 513 instead, 4096 is < 513*8 so happiness should return
and all should be right with the world.   At least for this one test.
(There was no problem on 64 bit systems as AuxInfo is bigger there.)
