[PATCH 3/4] bitbake.conf: Introduce variables used to access the other recipe specific sysroot directory in multilib case

[Kevin Hao <kexin.hao@windriver.com>]

When multilib is enabled, there would be two different recipe specific
sysroot directories:
  libxx-recipe-sysroot
  recipe-sysroot

We do need to access the files under the "recipe-sysroot" directory in
some cases. So introduces these variables for this purpose.
