Comment (by Sebastian Huber):

 The GCC -mcpu option changes the default values of other options such as
 -mstrict-align. You can have a look at the GCC sources:

 If you have problems with an alignment exception on a -mcpu=7400 based
 BSP, then simply add the -mstrict-align to this BSP. Other BSPs should
 remain as is.
