1.0.38.11: Enable floating-point exception delivery on PPC/Linux.

  * For some reason, Linux disables floating-point exception delivery
by default.  Use the PR_SET_FPEXC prctl (new in 2.4.21 and 2.5.32) to
enable it in "precise" mode (possibly overkill).

  * This is necessary but not sufficient to fix one of the failing
tests in float.pure.lisp.

  * Given that this is only necessary for one test case, the test
suite has woefully incomplete coverage of floating-point exceptions.
