Consider to fix the header files. To clarify, kfreebsd-kernel-headers provides sys/extattr.h, which declare the BSD-ish extended attributes prototypes, but for which there is no corresponding implementation in libc0.1, not even stubs. Moreover, libc0.1-dev provides sys/xattr.h with the Linux-ish prototypes, but those are merely stubs in libc0.1 returning -1 with errno set to ENOSYS. It probably makes sense to use the BSD-ish ones given they are a slightly different interface and are OS-specific APIs, in which case libc0.1 should gain implementations for them, though alternatively the Linux-ish ones could be used and sys/extattr.h dropped for (non-libc) userspace.
