I'm not clear if there is a specific question here, or a patch needing 
review.  In <https://gcc.gnu.org/ml/gcc-patches/2018-11/msg02106.html> I 
noted a specific issue: TOOL_INCLUDE_DIR should be a non-sysrooted prefix.

Also, could you clarify what, in the patch 
<https://gcc.gnu.org/ml/gcc-patches/2018-11/msg02089.html> (if that's 
still the current version),

> +  add_sysrooted_hdrs_prefix (&prefixes, argv[2], NULL, 0, 0, false);

is doing (that is, examples of what sort of prefixes it's adding)?
