flac-1.1.1 completely broken on linux/ppc and on macosx if built with the standard toolchain (not xcode)
Sadly the latest optimization broke completely everything.
The asm code isn't gas compliant. the libFLAC linker script has a typo,
disabling the asm optimization and/or altivec won't let a correct build
anyway.
Instant fixes for the asm stuff:
sed -i -e"s:;:\#:" on the lpc_asm.s
to load address instead of addis+ori you could use
lis and la and PLEASE use the @l(register)
