I investigated this a little:

* Using -shared-libgcc is always safe, as it has no effect if no
  shared libgcc was built.  So I am not going to make further patches
  to the Makefiles.

* g++ and gcj try to always use -shared-libgcc.  I didn't investigate
  why we need -shared-libgcc for the libjava executables (maybe I
  screwed up or maybe there is a bug in gcj).

* However, gcc does not use -shared-libgcc by default.  That is why we
  have to pass it in boehm-gc and libffi (I discovered this evening I
  forgot to check in the libffi patch -- expect it soon)
