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: https://bugzilla.redhat.com/show_bug.cgi?id=593363
