Yes, as it says in the FAQ I linked to earlier, you need to ensure the runtime linker can find the libraries. How to do that is not in scope for GCC but it is documented at http://gcc.gnu.org/install/configure.html under the --with-gmp, --with-mpfr, --with-mpc etc. options and LD_LIBRARY_PATH is suggested. If you use my config-gcc.mk then those libraries are linked statically and it all just works, without using ldconfig or LD_LIBRARY_PATH or anything else.
