[Fedora-packaging] %bits macro?

[Orion Poplawski]

It might me useful to have a %bits macro automatically set to 32 or 64 
as appropriate.  Does this seem useful or is there a better way?

I'm try to follow the following tip from 
http://fedoraproject.org/wiki/PackagingDrafts/MultilibTricks:

#if __WORDSIZE == 32
#include "myautoconfig-32.h"
#elif __WORDSIZE == 64
#include "myautoconfig-64.h"
#else
#error "Unknown word size"
#endif

So in my spec I want to move "myautoconfig.h" to "myautoconfig-32.h" (or 
64) as appropriate.  Would be nice to do:

mv myautoconfig.h myautoconfig-%{bits}.h

Thoughts?
