binutils: replace hard-links with soft-links to fix rpath
binutils installs its binaries both as bin/<tuple>-<tool> and as <tuple>/bin/<tool>, and hardlinks are used to reduce disk space consumption. This causes a problem for host-binutils with our rpath fixing logic done by "make sdk". Indeed, the fix-rpath script starts by fixing up the rpath of bin/<tuple>-<tool>, and sets the RPATH to $ORIGIN/../lib/. Then fix-rpath moves on to <tuple>/bin/<tool>, and doesn't find the library the tool depends on, and clears the RPATH. The result is that the binutils tool are not usable. Note that this is only visible currently on the ARC architecture, because on this architecture, binutils is fetched from git, which causes host-flex to be built, and some binutils tools to use the libfl shared library. Therefore, the binutils tools don't use just the standard C library (which is provided by the system) but also libfl from $(HOST_DIR)/lib, and therefore if the RPATH isn't set correctly, those tools don't work properly. In order to address this, this comit adds a post-install hook to host-binutils that replaces those hard links by symbolic links. It is worth mentioning that library loading and RPATH usage occurs *after* resolving the symbolic links, which makes this solution work.
