Found the cause:

"Back in October 2004, I did a bit of work on FLAC to get version 1.1.1 to
build correctly under GNU/Linux/PPC. Only now have I realised that somewhere
along the way something broke in FLAC's decoding. On my machine, roughly 50%
of FLAC files are being decoded incorrectly" -- John Steele Scott

"since it is going to take me a while to sort this out, and since
we need to get a release out to fix the sonames problem, I have
disabled PPC asm functions for now and will get back to it after
the release.  the static binaries I make for the darwin binary
release will have them though, because it's easy for me to
compile the right one" -- Josh Coalson


I suspect that PPC/Altivec asm code is disabled for good.
