Subject: [PATCH 1/2] Make dynamic linker a relative symlink to libc

absolute symlink into $(libdir) fails to load in a cross build
environment, especially when executing qemu in usermode to run target
applications, which cross build systems often do, since not everything
can be computed during cross builds, qemu in usermode often comes to aid
in such situations to feed into cross builds.

V2:
 Make use of 'ln -r' to create relative symlinks, as most fo the distros
 shipping coreutils 8.16+
