Details:

I'm seeing test failures in the symbolic package when built on some non-x86
architectures including ppc64, s390x:

octave -H -q --no-window-system --no-site-file --eval 'r=octsympy_tests; if r,
type octsympy_tests.log; end; exit(r)'
Symbolic pkg v2.7.1: Python communication link active, SymPy v1.3.
Integrated test scripts:

>>>>> processing @double/chebyshevU.m
***** test
 % s matrix, x scalar
 t = [1 2 sym(pi); exp(sym(1)) 5 6];
 y = sym(2);
 s = double (t);
 x = 2;
 A = chebyshevU (s, x);
 B = double (chebyshevU (t, y));
 assert (A, B, -eps);
!!!!! test failed
ASSERT errors for:  assert (A,B,-eps)
  Location  |  Observed  |  Expected  |  Reason
   (2,1)       38.6409      38.6409      Rel err 3.6777e-16 exceeds tol
2.2204e-16 by 1e-16

This is on Fedora Rawhide with octave 4.4.1.
