[xml] [PATCH] Fix yet another --with-threads bug: using "pipe" instead of "logical OR"

["Andrew W. Nosenko" <andrew w nosenko gmail com>]

Unfortunately, at the time of writing
    2bdf87e Restore behavior of --with-threads without argument

I was too concentrated on --with-threads without arguments and left
second problem in this check unattended: the test chain was built using
'|' pipe instead of '||' logical OR.

As consequence, case --with-threads=pthread remained broken, and
enabling threads by default become broken if neither --with-threads nor
--without-threads passed to configure at all.

* configure.in: use '||' for "logical OR" operator as it should to be
instead of '|' (pipe).
