[Ralf Wildenhues]

* doc/autoconf.texi: Merge variable index `vr' into concept
index using syncodeindex.
* doc/autoconf.texi (Configuration Actions, Generic Programs)
(Generic Functions, Initialization Macros, Writing Testsuites):
Add index entries for documented shell variables used during
in configure and testsuite scripts.  Fix entry for `tmp'.
