build: Bump _XOPEN_SOURCE to 700
On FreeBSD, macros such as _POSIX_C_SOURCE and _XOPEN_SOURCE are used as
a means to disable features instead of enabling features. Therefore,
setting a macro to a value which is too small can make required features
become unavailable.
Commit f57bec3322921631c322b7d151fb129125b9d80d sets _XOPEN_SOURCE to
500 and causes compilation errors on FreeBSD because of missing C99
support. FreeBSD libc automatically sets _POSIX_C_SOURCE to 199506 when
_XOPEN_SOURCE is set to 500. Since 1995 < 1999, this also means all C99
functions are disabled. To fix it, use a value matching the current
definition of _POSIX_C_SOURCE=200809, which is _XOPEN_SOURCE=700.
