Installation of Binutils This package is known to behave badly when you have changed its 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: mkdir ../binutils-build && cd ../binutils-build && ../binutils-&binutils-version;/configure --prefix=$LFS/usr --disable-nls && make LDFLAGS=-all-static tooldir=$LFS/usr && make tooldir=$LFS/usr install
