N.B. having to set LD_LIBRARY_PATH is ***not*** a good solution, and I
hope any writeup which suggests doing that will be rejected. The
simplest solution is to install GCC from pre-built packages from
someone who knows what they're doing, the next best is to link to gmp,
mpfr and mpc statically so LD_LIBRARY_PATH is not needed.

The worst, least reliable method is to require LD_LIBRARY_PATH to be
set when running the compiler.

Unfortunately everyone who tries to build the compiler thinks that
installing gmp, mpfr and mpc in /some/path/to/libs is a good idea,
then gets stuck, then discovers that LD_LIBRARY_PATH unsticks them,
and thinks that's a good solution.
