Add -Wno-narrowing to CXXFLAGS for gcc.
This removes warnings of the form
warning: narrowing conversion of X from 'int' to 'float' inside { } is
ill-formed in C++11 [-Wnarrowing]
in ff_fragment_shader.cpp and gen6_blorp.cpp of the form. When building
i965, I observed no other difference in the build output.
