Is there any harm in keeping it here?

While it really is a redifinition, I'm not sure what's the right thing
here.  This whole code is not from qemu, it is an external source imported,
and that source is being maintained (but under different license as has
already been discussed, so keeping changes at minimum might not be that
good idea anymore).  On the other hand this symbol is so common it should
be defined in a common header.  Yet on another hand, for these external
sources wich has public API, it might not be a good idea to define it in
a header to start with, because it might clash with project-local define,
so it might be better to define it in either private header or in individual
source.

Oh well, so much for so trivial thing... ;)
