I realised this is a good job for atreus, since it can compile
xapian-core from scratch in about 90 seconds.

The commit at which it stopped working is much older than I expected:

Fix detection of valgrind for newer valgrind.  My version of valgrind
(valgrind-3.2.1-Debian, from ubuntu feisty) treats the parameter supplied to
--log-file as a base path, and appends a process ID. This caused the test for
the log-file option to fail with permission denied errors due to trying to
write to files of the form '/dev/null.16098'.  Solution - test for the
--log-file-exactly option, and use that.  Also, change configure.ac to display
the result of the tests for valgrind; was displaying that it had found it, but
not mentioning that it couldn't make it work.

However, I don't believe this is actually the cause of the problem, since
this change just fixes configure to actually successfully detect modern
versions of valgrind.

Cheers,
