[gentoo-dev] [PATCH] linux-info.eclass: account for lack of trailing slash

[Marty E. Plummer]

In EAPI 7, D, ED, ROOT, EROOT no longer have a trailing slash[1]. This
makes finding /usr/src/linux not work properly as it currently stands.

Use the form "${ROOT%}/" where apropos in order to unify behavior across
EAPIs.
