If we weren't using libtool, it would be better to eliminate this and
instead special case the linker in libjava's Makefile.

But using libtool, it is basically a catch-22 (you need C++ in
configure, but then C++ goes in the libtool script, and then you cannot
eliminate it from the makefile).

If it bothers you (does it cause a PR?), I think it's easiest to define
a cache variable somewhere so that the test is forced to pass.  Anyway
you know you do not need to build C++ executables (only Java) in libjava.
