My build completed, and have no new test failures (make check).

I haven't verified, but setting UMFPACK_LIBS and then running configure or 
passing UMFPACK_LIBS to configure should resolve this.

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

or

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