perf doc: Pass ASCIIDOC_EXTRA as an argument

commit e9cfa47e ("perf doc: allow ASCIIDOC_EXTRA to be an argument")
allowed ASCIIDOC_EXTRA to be passed as an option to the Documentation
Makefile. This change passes ASCIIDOC_EXTRA, set by detected features or
command line options, prior to doing a Documentation build. This is
necessary to allow conditional compilation, based on configuration
variables, in asciidoc code.
