Subject: [PATCH] Warn on undefined components in buildtree macros
Issue a warning if buildtree macros (%_sourcedir etc) contain undefined
macro(s) after expansion, such as things only defined during spec parse.
This always was a murky case that doesn't work in all scenarios, so
a warning seems appropriate. Actual behavior doesn't change here though.
