Question About Building Newer GCC To Co-Exist With The System One

I work on a SLES11 server and I am trying to build a newer GCC compiler and 
use it to build a large set of tools.  The system compiler is GCC 4.3.4 and I 
am building GCC 4.8.1.  While doing sanity tests, I noticed something strange 
with the GCC 4.8.1 compiler that I built.  Some of the binaries are linked to 
the system libgcc_s.so and others are linked to the one built for the GCC 
4.8.1 compiler.  For example: 

ci1admin@dtcci1devbal801:/opt/ci1/toolchain/tc8.2/sles11sp1_gcc-4.8.1_x86-
64/gcc-4.8.1/bin> ldd gcc | grep libgcc_s
        libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f57377f2000)

ci1admin@dtcci1devbal801:/opt/ci1/toolchain/tc8.2/sles11sp1_gcc-4.8.1_x86-
64/gcc-4.8.1/bin> ldd gappletviewer | grep libgcc_s
        libgcc_s.so.1 => /opt/ci1/toolchain/tc8.2/sles11sp1_gcc-4.8.1_x86-
64//gcc-4.8.1/lib/../lib64/libgcc_s.so.1 (0x00007f10052ff000)

Is this intentional or is this due to something I am doing during the build 
process ?
