And from Wikipedia RISC-V: `An execution environment interface may allow 
accessed memory addresses not to be aligned to their word width, but accesses 
to aligned addresses may be faster; for example, simple CPUs may implement 
unaligned accesses with slow software emulation driven from an alignment 
failure interrupt.`

RTEMS is definitely not doing this emulation as RTEMS_EXCEPTION_EXTENSIONS is 
only supported on microblaze and aarch64.
