configure: Account CXXFLAGS in gcc-plugin.m4.
We now use a C++ compiler so that we need to process CXXFLAGS as well as CFLAGS in the gcc-plugin config fragment. Signed-off-by: Iain Sandoe <iain@sandoe.co.uk> config/ChangeLog: * gcc-plugin.m4: Save and process CXXFLAGS. gcc/ChangeLog: * configure: Regenerate. libcc1/ChangeLog: * configure: Regenerate.
