Once i used CLFAGS=-O2 -fno-strict-aliasing -pipe and it failed,
other time I used CFLAGS=-Os -pipe and it also failed

I have compiled everything with the previously mentioned CFLAGS and
the system runs fine (only a problem with using RUM, however I think
that is driver related, not compile flags related)

The ports that are affected by strict-aliasing, are they not protected
(i.e. force -fno=strict-aliasing?)

I'll try some experiments to see if I can isolate the problem
