sys-fs/sysfsutils is broken and dead upstream. Dependency on it needs to be
removed so we can remove it from the tree.
I noticed libsysfs is not essential for this package to compile. Is it even necessary for all the package's tools to work? I don't really know how to use the package, but when I compile openhpi-3.2.0 with libsysfs support, it only has one more file with the u+x bit (plugins/sysfs/.libs/libsysfs2hpi.so.3.2.0) when compared to compiling it without libsysfs support.
I mean to say: it looks like libsysfs might be just one of the possible means of accessing something - and thus a replaceable means. But I don't know how to use the package. Just a hint.
