you are using a custom toolchain installed in /usr/local that is not set
up correctly.
various GCC headers and glibc headers with the same name include each
other via #include_next, and that doesn't work in your case for whatever
reason, the file /usr/include/math.h that defines a ::isnan (or isnan as
a macro, in case of Fedora 24) isn't included.
you could spend some hours looking at preprocessor output and tweak
include paths to get that to work, or you could just use the GCC shipped
in your distribution which presumably works.
