[ELPA Syncer]

branch: externals/system-packages
commit f937f03f43e5a65685f3ca71616af29fe0dda95e
Author: Jake Shilling <shilling.jake@gmail.com>
Commit: Jake Shilling <shilling.jake@gmail.com>

    Use eix to search when available
    
    On the emerge backend, use `eix` to search if found in `exec-path`. This
    allows for faster searching than using `emerge -S`.
