Commit 24e03369 authored Oct 17, 2014 by Ying Wang

Add -Wno-unused-command-line-argument to clang cflags to enable ccache.

Previously ccache is disabled when it fails calling clang's preprocessor with
unused arguments (such as '-Wa,--noexecstack') in the command line.

See http://petereisentraut.blogspot.com/2011/05/ccache-and-clang.html.
(-Qunused-arguments suppresses more than
-Wno-unused-command-line-argument does.)
