I am a bit confused here.
I've built r16-8253-geb50d28a9353e9 with the following commands:
$ mkdir build
$ cd build
$ ../gcc/configure --prefix=$PWD/../install --disable-multilib
--enable-languages=c,c++ && make -j8 && make install
$ cd ..
$ mkdir test
$ cd test
$ cat > site.exp <<EOF

set host_triplet x86_64-pc-linux-gnu
set build_triplet x86_64-pc-linux-gnu
set target_triplet x86_64-pc-linux-gnu
set target_alias x86_64-pc-linux-gnu
set libiconv ""
set CFLAGS ""
set CXXFLAGS ""
set HOSTCC "gcc"
set HOSTCXX "g++"
set HOSTCFLAGS "-g -O2 "
set HOSTCXXFLAGS "-g -O2 "
set HAVE_LIBSTDCXX_V3 1
set ENABLE_PLUGIN 1
set PLUGINCC "g++"
set PLUGINCFLAGS "-g"
set tmpdir $PWD/test
set srcdir "\${srcdir}/testsuite"

Am I missing something here?
