This is tricky, because autoconf provides no way to do this automatically (AC_PROG_CXX fails if no C++ compiler). One could override AC_MSG_ERROR/FAILURE for AC_PROG_CXX, but that causes all sorts of problems later (like sys/types.h not found). So instead create yet another configure in libclamav/c++, but teach autoconf not to fail if the subconfigure fails (by overriding AC_MSG_ERROR to set a variable instead of exiting). This seems to work with shared and static builds, "-all-static" builds don't work yet, will fix that later.
