The "configure.cxx" option is meant to directly set the CXX environment
variable for the configure stage. Technically it is possible to add
traces to it to add dependencies automatically, which would be the
inverse of what we currently do (explicitly specify the compiler
collection and update configure.* accordingly). That might be fragile,
though.
