For reasons that are still unclear, the 'ncbss' region was overlapping the "audiobuffer" when linked with 2.21, but okay with 2.20. Fixed it by making the audiobuffer explcitly use the current position instead of relying on it being implicit. With this change, portalplayer-based targets generate working binaries when built with binutils 2.21 or newer. This bug also theoretically affects imx233/imx31 targets as they also have NOCACHE_BASE games in their linker scripts, but I lack access to one to test with.
