configure.html does say:
--enable-build-poststage1-with-cxx
     When bootstrapping, build stages 2 and 3 of GCC using a C++ compiler
     rather than a C compiler. Stage 1 is still built with a C compiler.
     This is enabled by default and may be disabled using
     --disable-build-poststage1-with-cxx.

There are other hints like the default value of --with-boot-ldflags which 
includes -static-libstdc++.

build.html doesn't say anything. Options have to be passed through 
BOOT_CFLAGS which doesn't look much like CXX, but then it doesn't matter.
