    buildsystem: Fix libfoo.so links for /lib libraries
    
    * When installing to a non-default location by using DESTDIR on the make
      installworld command line, /usr/lib/libfoo.so links pointed to wrong
      locations
    
    * DESTDIR is used both as an installworld parameter and internally by the
      build system and these two cases expect different behaviors
    
    * Symlinks locations in /usr/obj must be relative to the host (builder)
      filesystem namespace
      libc.so -> /usr/obj/usr/src/world_x86_64/lib/libc.so
    
    * Symlinks locations in the final destination directory must be relative to
      the target world filesystem namespace
      libc.so -> /lib/libc.so
    
    * The symlinks themselves must be absolute in order to not break
      installations where /usr is a symlink
    
    Inspired-by: FreeBSD's historical transition to /lib
