Non-default Mono installations still need LD_LIBRARY_PATH, otherwise
p/invoke of Mono libraries (libgdiplus, libMonoPosixHelper) won't
work because p/invoke is obeying the CLR rules of library look-up
that know nothing about ELF RPATH attributes.

Moreover, things like pkg-config need to be configured as well,
because they also know nothing about mono's executable RPATH.

The only thing you'd achieve by setting the RPATH attribute:
you won't be able to safely relocate Mono anymore, as RPATH
takes precedence over LD_LIBRARY_PATH.
