Hard to say without the entire spec, but one typical cause of "sometimes 
works sometimes doesn't" issues with macros are %define's inside macro 
{} blocks, which "work" until the first parametrized macro is called, 
and after that it doesn't (due to an ancient flaw in the macro engine). 
Replacing the %define inside {} with %global helps in this case.

Another possibility that comes to mind is funny side-effects from 
BuildArch which can cause similar effects, but this time use of %global 
being the problem:
