meta-phosphor: Create obmc-autotools to update AR and RANLIB
Many recipes are turning on -flto which causes issues
with the linker when dealing with libraries. It was suggested here
http://stackoverflow.com/questions/25878407/how-can-i-use-lto-with-static-libraries#comment67660913_25878408
to use the gcc wrappers to deal with this problem. Create flto-automake
class as this seems like something that could be globally applied
if needed.
Tested-by: phosphor-pid-control began to build, saw no new build
issues.
