when oggenc is run, it appears to always eventually crash:
cpu% audio/oggenc < /dev/zero > /dev/null
cpu% echo $status
oggenc 4556069: abort
the abort occurs due to free() called on a corrupted malloc()'d buffer
inside of libvorbis.
this call to malloc was inserted as a replacement for alloca(), which
of course we don't have. perhaps this bug was always in this code, but
never noticed since it might just trash autos on the stack.
