Every time oe.elf.machine_dict() is called a large dictionary is created and returned. However, the "arch" package_qa test will call this method for every binary in a package, which results in a lot of dictionary creation. Concrete exmaple: in running ltp:do_package_qa, the arch test takes 25% of the runtime, and opitimising the machine_dict() call to cache the generated dictionary reduces the runtime from 57s to 44s.
