Hi, That newer version of flac makes use of getauxval(3) on powerpc, that apparently we don't implement, so the builds fails while not finding sys/auxv.h.
The below diff allows to build flac on macppc, where tests are passing [1]. I've not bumped revision, the change impacts powerpc where it has never been built. Comments/feedback are welcome, Charlène.
