[v4] HOST_DIR/lib: symlink respectively to lib32/64

Discovered the issue on a RHEL7.4 machine where
the cmake build dynamically selected HOST_DIR/lib64
as the installation path for the lzo2 library.

Fixes failures like the following:
host-mtd
http://autobuild.buildroot.net/results/d31/d31581d2e60f35cf70312683df99c768e2ea8516/

host-squashfs

Changes:
[Arnout
v3 -> v4
 - Added @ infront of case statement
 - Handled case of HOST_DIR ends up being newer and ln -s
   would create a link inside of the lib folder.  Add -nf
   to the args of ln (ie. ln -snf)

[Yann
v2 -> v3
 - Updated hostarch logic to check for 64bit in the name
   and if present create link.  This supports all archs
   vs just x86.

v1 -> v2
 - Correct the condition used to determine host arch.
   (Previously used the target arch check)
