Probably because you weren't running it with prove:

$ prove -v /usr/tests/lib/msun/fmaxmin_test

All tests successful.
Files=1, Tests=12,  1 wallclock secs ( 0.06 usr  0.28 sys +  0.00 cusr  0.02
csys =  0.37 CPU)
Result: PASS

The check needed to be converted from a build time compiler check to a compile
time check because unfortunately the build would break when building 11.x on a
10.3 system, for example.
