You can remove ' in '#f and '#t here.
That shouldn't cause a derivation change.
Keeping ' is harmless though, it's just superfluous.
Likewise for some other commits.

I'm not really familiar with powerpc and the packages you modified,
so I'm just looking at style, and cross-compilation issues (which you seem
to have covered).
