1) Linux is LP64 so sizeof(long) and sizeof(pointer) always match, so it's not
truncating.

2) The sh5 only ever shipped evaluation units, it never had a production run,
and we haven't implemented j64 yet, so all superh targets are currently 32 bit.
(I.E. it's complaining about _expanding_ the pointer, which shouldn't be a
problem as long as endianness is respected.)
