This package is known to behave badly when you have changed it's default optimization flags (including the -march and -mcpu options). Binutils is best left alone, so we recommend you unsetting CFLAGS, CXXFLAGS and other such variables/settings that would change the default optimization that it comes with. Install Binutils by running the following commands: ./configure --prefix=$LFS/usr --disable-nls && make LDFLAGS=-all-static tooldir=$LFS/usr && make tooldir=$LFS/usr install
