For info: The Linux support here is incomplete, e.g., mapping to
`__nexttoward_to_ieee128` is not present.
If it is not too much trouble for FreeBSD's libc to match glibc math function
symbol names, then doing so will actually help to mitigate issues tied to
limited usage of Clang on Linux (compared to GCC).
