Gregory Szorc c7c65f2fb5 Bug 1321750 - Remove automatic color flags from HOST_CFLAGS, HOST_CXXFLAGS; r=glandium 
moz.configure only sets the color flags value for the target compiler.
If the host compiler is a different version and doesn't support color
flags, we may pass unrecognized command line options.

Until we have better distinction between host and target compilers
throughout the build system, just disable automatic color flags for
host invocations. We don't have too many host binaries, so this should
have negligible impact.
