Is this really the right thing to do? Ideally a program written in C
should not have to know that a library it is using is written in C++.

We already had a similar situation in Buildroot, and so far we have
added -lstdc++. For example:

ifeq ($(BR2_PACKAGE_DIRECTFB),y)
LINKS_CONF_ENV = ac_cv_path_DIRECTFB_CONFIG=$(STAGING_DIR)/usr/bin/directfb-config
ifeq ($(BR2_STATIC_LIBS),y)
LINKS_CONF_ENV += LIBS=-lstdc++

and there's a few other examples in the tree. To be honest, I don't
know what is the most correct solution, I'm just trying to make sure we
solve a given problem in the same way everywhere.

Best regards,

Thomas
