Add /usr/local/GCC/lib to your LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/GCC/lib

There is probably a way to reconfigure your linker to check this
    directory without using LD_LIBRARY_PATH. Under freebsd or linux
    see 'man ldconfig' On other unices you'll have to do your own
    searching.
