Fix portability issue in tests from commit ce773f230.

Browse Source 
Modern POSIX seems to require strtod() to accept "-NaN", but there's
nothing about NaN in SUSv2, and some of our oldest buildfarm members
don't like it.  Let's try writing it as -'NaN' instead; that seems
to produce the same result, at least on Intel hardware.

Per buildfarm.
