multilib trouble with java

[Geoff Keating <geoffk at geoffk dot org>]

Between revision 114610 and 114633, GCC trunk started failing to  
build on powerpc-darwin, with this error:

ld64 warning: in /Users/regress/tbox/objs-20050712/lib/libgcj.dylib,  
file is not of required architecture
can't resolve symbols:
  _JNI_CreateJavaVM, referenced from:
      _main in gappletviewer-toolwrapper.o

The problem is that it's not being properly bootstrapped;  
objs-20050712/lib/libgcj.dylib is the libgcj.dylib in the system  
compiler, not the one that was just built.

I'm guessing this is due to this change:
