Hello,

although setting CFLAGS_FOR_TARGET before compiling gcc works fine,
CXXFLAGS_FOR_TARGET is ignored. I don't see any good reason for that.

I tested the patch by doing a regular bootstrap+testsuite on
x86_64-unknown-linux-gnu. I also did a non-bootstrap build where I set
CXXFLAGS_FOR_TARGET and checked that it now propagates to libstdc++
and others.

    * mt-gnu: Don't reset CXXFLAGS_FOR_TARGET.

OK for the trunk.  Please install.
