You MUST build it as an 32-bit GCC, not 64-bit GCC. I am using CC="gcc -fno-lto -m32" CXX="g++ -fno-lto -m32" BOOT_CFLAGS="-g" BOOT_CXXFLAGS="-g" CFLAGS="-g" CXXFLAGS="-g" RUNTESTFLAGS="--target_board='unix'" /export/gnu/import/git/sources/gcc/configure --enable-languages=c,c++ --disable-bootstrap i686-linux --prefix=/usr/gcc-7.0.0 --with-local-prefix=/usr/local --enable-gnu-indirect-function --enable-libmpx --disable-libcc1 --disable-libcilkrts --disable-libsanitizer --enable-clocale=gnu --with-system-zlib --with-demangler-in-ld --with-fpmath=sse on x86-64.
