It says this:
configure:5531: checking for __cxa_demangle in -lstdc++
configure:5556: gcc -o conftest -m32 conftest.c -lstdc++ >&5
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-linux-gnu/4.9/libstdc++.so when searching for -lstdc++
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-linux-gnu/4.9/libstdc++.a when searching for -lstdc++
/usr/bin/ld: cannot find -lstdc++
collect2: error: ld returned 1 exit status
configure:5556: $? = 1
configure: failed program was:
[skip]
configure:5565: result: no
Both
./configure CFLAGS=-m32
./configure --build=x86_64-linux-gnu --host=i386-linux-gnu
--target=i386-linux-gnu CFLAGS=-m32
gives the same result.
