I'm pretty certain I see the issue now.  I put "SUBDIRS += gnulib/lib"
inside the "if BUILD_C_CODE" condition.  This was to avoid building the
gnulib library, pointlessly, if the XS modules weren't going to be used.

Hence, any other C objects (libraries, programs) that link against gnulib
need to be governed by the same condition.
