Subject: [PATCH] Add missing directories in Build Config node of manual

The 'Installing Site Packages' node of the Guile manual mentioned
looking into the 'Build Config' node for information on the extensions
dir, but that node does not mention the extensions dir at all. Some
others that are also missing are added.

* doc/ref/api-options.texi (Build Config): add ccachedir, extensionsdir,
and CFLAGS to the available information from %guile-build-info.
