Oh, this is surprising.

The compilation of malloca.c should be enabled here:

ifeq (,$(OMIT_GNULIB_MODULE_malloca))

ifneq (,$(gl_GNULIB_ENABLED_malloca))
libgnu_a_SOURCES += malloca.c

EXTRA_DIST += malloca.h


1) Can you please verify that nothing defines the Makefile macro
   OMIT_GNULIB_MODULE_malloca in your build?
2) What are the values of HAVE_CANONICALIZE_FILE_NAME and
3) I'd need to see why gl_GNULIB_ENABLED_malloca is not getting set.
   Can you please run "make distclean", rerun configure with shell tracing:
     sh -x ./configure ... 2>&1 |tee config.shlog
   and attach the generated config.shlog file as well as config.log, 
   and the configure script (in compressed form)?
   I hope I can understand the cause by looking at this log.
4) Also, it would help to know why the linker is not complaining about
   a missing '_mmalloca' symbol.
   $ nm lib/canonicalize-lgpl.o | grep malloca
   $ for f in `find . -name '*.o'`; do echo $f ; nm $f | grep malloca ; done
