doesn't have provider 'cc' error with bazel-0.25.0

Lines 128 to 130 in d642038

	compile_flags = (compiler_options +
	target.cc.compile_flags +
	(ctx.rule.attr.copts if "copts" in dir(ctx.rule.attr) else []))

It's from the line 129, target.cc.compile_flags, which is now deprecated (from bazel-0.25.0). Please see bazelbuild/bazel#7036 for details. I think a solution is to use get_compile_flags(target) instead of target.cc.compile_flags. AFAIK, get_compile_flags is not included in bazel so we need to copy/paste it from https://gist.github.com/oquenchil/7e2c2bd761aa1341b458cc25608da50c.

Thank you for the report. I will most likely look at all bazel 0.25 compatibility issues in the coming weekend.

This is now fixed through 4a1469a and included in release 0.3.4.

Thank you for your patience.
