I have no idea why configure is trying to run the test in your case, but I just yesterday
updated master's gnulib copy to current upstream gnulib master.  Previously we had
a 2012 copy.  I don't see any AC_TRY_RUN in current master, for instance,
though I didn't check older versions.  In any case, try seeing if current master makes
a difference.
