libtree for linux portable?

[jb_fvwm2]

github link

It won't run unported on my system. [ 'a better ldd' ]

Nm, reading github it has linux-specific files... afaik

With minimal patching, it kinda work.
What I did install: devel/cxxopts, devel/termcolor, devel/elfio
For patching:
Creating directory: /usr/local/share/elfio/cmake

And adding the file: elfioConfig.cmake, elfioConfigVersion.cmake, elfioTargets.cmake from a cmake build directory of elfio (don't know why elfio didn't install them, maybe they used autoconf for the ports tree)

And finally since AT_PLATFORM is not defined (and I didn't bother to check where is getauxval), here is a patch for libtree
