Then maybe you need to run ldconfig or reboot to update the cache.

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.
