That is an excellent point, one which I had not fully considered.

One way to deal with this (properly even), would be to have the 'gcc' 
compiler driver pass in a -L option that indicates the location of the 
bytecode-libs directory.  It already passes in -L options for 
"lib/gcc/<target>/3.4-llvm/" and others, so this should be pretty easy.
