I used

CC="gcc -mx32 -fno-lto" CXX="g++ -mx32 -fno-lto"
RUNTESTFLAGS="--target_board='unix{-m64,-m32,}'"
/export/gnu/import/git/sources/gcc/configure --with-demangler-in-ld
--enable-languages=c,c++,fortran,lto,objc,ada,obj-c++,go 
--prefix=/usr/gcc-8.0.0-mx32 --with-local-prefix=/usr/local
--enable-gnu-indirect-function --enable-clocale=gnu --with-system-zlib
--enable-checking=yes,rtl --enable-libmpx --with-multilib-list=m32,m64,mx32
--enable-linker-build-id --enable-gnu-unique-object --with-abi=mx32
--with-fpmath=sse

--with-abi=mx32 will bootstrap GCC in x32.  You need to make sure that
linker in x32 is your PATH.  I have

[hjl@gnu-4 kernel]$ file /usr/localx32/bin/ld
/usr/localx32/bin/ld: ELF 32-bit LSB executable, x86-64, version 1 (SYSV),
