So hw_error is depracated in it's own right so I was thinking it stands alone.

But the idea that actually prompted it was I was looking at arch-obj
undef symbols from the multi-arch compile to see how much these TCG
modules depend on core code for linkage. The idea was to minimise
core-code linkage deps of the modules, so a TCG translator could be
linked to something that is not QEMU. This is ambitious and I have
since shelved the idea as it is a huge project. But once you accept
glib and the QOM core need to come with, it is a half sane list of
APIs you need to implement to link TCG to something new.

hw_error() stuck out like a sore thumb as a core-defined symbol I
could get rid of from target-arm arch-obj and reduce that API by one
symbol.
