CC="gcc -m32 -O2" CXX="g++ -m32" /export/gnu/import/git/gitlab/x86-binutils/conf
igure \
\
--target=cris-axis-linux-gnu \
--enable-plugins --disable-gdb --disable-gdbserver --disable-libdecnumbe
r --disable-readline --disable-sim --with-sysroot=/ --with-system-zlib \
--prefix=/usr/local \
--with-local-prefix=/usr/local
