[Xen-devel] [PATCH 6/9] docs/Makefile: Introduce GENERATE_PANDOC_RULE_RAW

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

We are going to want to format SUPPORT.md which does not match the
filename patterns in docs/.  So provide a way to make an ad-hoc rule
using pandoc with the standard options.

No functional change in this patch.
