You need both the default 64-bit and the optional 32-bit C library in sysroot, the 64-bit
libraries in 'lib64' & 'usr/lib64' and the 32-bit libraries in 'lib' & 'usr/lib'. You maybe
installed only the 32-bit ones?

But the 'libc.so' normally isn't a binary file but a text file, a linker script, which puts
the linker to link against the 'libc.so.6' and 'libc_nonshared.a' and maybe 'ld-linux.so.2'
(in the 32-bit case). So complaining about the script is a little odd. Please check the
situation in the '*lib64' and '*lib' directories.

If you don't need the 32-bit anywhere, the use '--disable-multilib' in the GCC configure,
then the build doesn't try to create the 32-bit 'libgcc', 'libstdc++' etc.

[Gaurav] - Just one thought is there some special  provision that needs to be done while building binary utilities so that ld is built using the libc present in sysroot rather than host system libc.

Btw following is my configure options for binutils 

AR=ar AS=as ${SOURCES_BINUTILS}/configure \
        --prefix=${CROSS_TOOLS} \
        --target=${TARGET} \
        --with-sysroot=${SYSROOT} \
        --disable-nls --enable-shared
