Support Library Requirements for GCC 10


Hi,

The minimum support library version of MPC for building GCC 10 is not
correct.

After downloading gcc-10-20191229.tar.xz and
  $ cd gcc-10-20191229/gcc/doc
  $ ./install.texi2html
  $ xdg-open HTML/prerequisites.html
I installed
  - gmp 4.3.2 - works,
  - mpfr 3.1.0 - works,
  - mpc 0.8.1 - fails!

The failure has been reported already in [1]. The fix is to use

  - mpc 1.0.3 - works.

This wastes some time for everyone who attempts to install GCC 10 from
scratch.

In [2] it was suggested to look in the contrib/download_prerequisites script.
This script indeed contains

  mpc='mpc-1.0.3.tar.gz'

Additionally, the mpc-0.8.1 release is so old that it is not (or no longer)
on ftp.gnu.org [3].

Therefore I would suggest
  1) to change the documentation (HTML/prerequisites.html) in the GCC 10
     snapshots to mention mpc-1.0.3 instead of mpc-0.8.1,
  2) likewise, change https://gcc.gnu.org/install/prerequisites.html
     to mention mpc-1.0.3 instead of mpc-0.8.1.
