This patch fixes a compilation error on FreeBSD, when I use
gl_cv_func_fesetexceptflag_in_libm=no \
gl_cv_func_fesetexceptflag_no_libm=no \
./configure
for testing the override code.

fenv-exceptions-state-c99: Fix compilation error on FreeBSD.
* lib/fenv.in.h (fegetexceptflag, fesetexceptflag): On FreeBSD, use an
rpl_ prefix, to avoid a conflict with an inline definition in FreeBSD's
<fenv.h>.
