I've been successful in resoling the problem by including -lSuiteSparse in the 
UMFPACK_LIBS variable.  Either ...

        ./configure UMFPACK_LIBS="-lumfpack -lSuiteSparse"

... or ...

        export UMFPACK_LIBS="-lumfpack -lSuiteSparse"
        ./configure ...

... should work.  What I've done so far was to edit liboctave/Makefile and add 
"-lSuiteSparse" to the UMFPACK_LIBS variable definition.  After that octave 
built without incident and "make check" returned no new failures.  I've started 
a fresh build starting to configure to check that everything works as expected. 
 If it does, I'll file a bug report (configure should check if -lSuiteSparse 
needs to be added to UMFPACK_LIBS).
