Richard Purdie 82233cd647 eglibc-options: Rewrite so it benefits from bitbake's contains handling 
Having eglibc rebuild every time DISTRO_FEATURES changes is suboptimal.
This rewrite takes advantage of bitbake's understanding of the contains
function so this doesn't happen. The code is marginally uglier but is
worth the benefit in fewer libc rebuilds.
