Solomon Peachy cd9906847b arm: Fix PortalPlayer linker scripts with binutils 2.21+
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.
