[gentoo-dev] [PATCH] udev.eclass: return unprefixed udevdir

[Guilherme Amadio]

Hi,

This is a simple fix, but I'd like it to be reviewed.

Without this get_udevdir returns the prefixed directory, leading
to double prefix on udev related packages (e.g. fuse-common).

Even if not used in prefix, udev related packages are usually pulled
in as dependencies of other packages (xrootd for fuse).

Cheers,
-Guilherme
