[PATCH 2/2] gcc: make Valgrind errors fatal with --enable-checking=valgrind

[Sam James]

Valgrind doesn't error out by default which means bootstrap issues like
in PR116945 can easily be missed: pass --exit-errorcode=1 to handle this.

        * gcc.cc (execute): Pass --error-exitcode=2 to Valgrind.
