Firstly, don't use ./configure to build GCC, see
https://gcc.gnu.org/wiki/FAQ#configure

Secondly, it is much easier to build gmp, mpfr and mpc directly in the
GCC tree, instead of installing them separately, see
https://gcc.gnu.org/wiki/InstallingGCC for how to use the
contrib/download_prerequisites script that means you don't need to use
--with-gmp and --with-mpfr and --with-mpc.

Thirdly, your paths look suspicious. The prefix for gcc, gmp and mpc
is .../soft/lib/ but the prefix for mpfr is .../soft/lib/packages ...
which is also the build path shown below. Make sure you are not trying
to build in the source tree, and are not trying to build in the
install location specified with --prefix.
