Since isl-0.22.1-359-g8b9f94f262 (build extract_interface
using build compiler, Thu May 21 14:55:46 2020 +0200),
the default C++ compiler is overridden by the build C++ compiler
inside interface. This was meant to ensure that the clang
configure checks are performed using the right compiler,
but those checking for libraries were being performed by
the (host) C compiler instead. Use the (build) C++ compiler
there as well.
