[PATCH] lto: use diagnostics_context in print_lto_docs_link

[Martin Liška]

Properly parse OPT_fdiagnostics_urls_ and then initialize both urls
and colors for global_dc. Doing that we would follow the configure
option --with-documentation-root-url, -fdiagnostics-urls is respected.
Plus we'll print colored warning and note messages.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin
