[gentoo-dev] [PATCH] xdg-utils.eclass: execute tools from PATH

[Mike Gilbert <floppym@gentoo.org>]

Avoid calling binaries that may have been compiled against different
libraries or even cross-compiled for an incomatible arch.

Also drop the related eclass variables: these are currently unused by
any ebuild.
