I built C only and static only, it looks like what is happening is that
CXX is getting set to the system C++ compiler because /usr/bin is in my
PATH after the directory where I built the 'partial gcc'.  The actual
link of links-dso-program doesn't seem to be using CXX though, it seems
to call CC (aarch64-linux-gnu-gcc) which is in my directory and which
has no corresponding C++ libraries.
