I patched hotspot/make/bsd/makefiles/gcc.make to remove this compiler
flag. That got me further, but still no joy:

Apparently this is some illegal C++ that neither gcc nor clang 3.3
complain about, but clang 3.4 flags.
At that point I picked up the USES_GMAKE and MAKE_ARGS changes from
openjdk7/Makefile and was able to build openjdk6. The same problems are
still in openjdk7, but it builds because it doesn't try to use clang.
