[gdb/build] Add CXX_DIALECT to CXX

(In reply to Tom de Vries from comment #1)

Patch implementing this.

Indeed now we have:
...
configure:8916: checking for std::thread
configure:8933: g++ -std=3Dgnu++11 -c -pthread -Wall -O2 -g     conftest.cp=
p >&5
configure:8933: $? =3D 0
configure:8940: result: yes
...
but indeed in the build/gdb/Makefile:
...
CXX =3D g++ -std=3Dgnu++11
CXX_DIALECT =3D -std=3Dgnu++11
...
