Clang: Silence warnings (1/3)
With GCC >=4.7 Clang generates a lot of noise with various compiler flags,
and can even break the builds when using Flags like Graphite. This can be
reproduced by doing the following:
Setting TARGET_EXTRA_CFLAGS with Graphite flags such as these
TARGET_EXTRA_CFLAGS += -fgraphite-identity \
-floop-block \
-floop-strip-mine \
-ftree-loop-distribution \
-ftree-loop-linear
Causes the following errors to occure and the builds to fail:
clang: error: argument unused during compilation: '-fgraphite-identity'
'-floop-block'
'-floop-strip-mine'
'-ftree-loop-distribution'
'-ftree-loop-linear'
Silence the errors by passing the -Qunused-arguments for CFLAGS
