Thanks! If I need to build ghc-rpm-macros twice (it doesn't seem to
build non-bootstrapped before the new ghc is built), where in the
process does the non-bootstrap build come? Or does it matter much?

The symptom I was seeing was segfaults, specifically in HsSyck.  Given
that I wasn't confident in my build, and had seen some anomalies while
working on it, I want to make sure that I have the stack properly built,
then try to chase down whatever might be wrong on the HsSyck side.
