The latest version of the binary utils package (which includes the assembler, linker, loader and archiver) may be required to build the latest glibc. If you need to build binutils, begin by downloading its source from http://www.gnu.org/software/binutils/.
Extract the source:
cd /rpm/binutils
tar -xvzf binutils-x.y.z.tar.gz
Then, configure and build the binary utilities:
./configure --prefix=/usr
make
Note that the default installation directory for configure is "/usr/local". However, many systems come with the binary utilities installed in "/usr". Hence, if you wish to replace older ones, the need to specify "--prefix=/usr".
Install the completed build as super user.
su
make install
