The implication is that many ac3/aac files no longer work.
Both e.g.
-demuxer real
or with latest SVN
-demuxer lavf -lavfdopts format=rm
should work around it.

The one you want to get rid of is "real", not "libavcodec".
"real" is the binary realplayer codecs which only exist for x86,
x86_64 and ppc so I have no idea what you'd want with that on an Xscale.
You'll probably want something more like
--disable-mencoder --disable-parser='.*' --disable-decoder='.*'
--enable-decoder=COOK_DECODER --disable-demuxer='.*'
--enable-demuxer=RM_DEMUXER
instead.
