Subject: [PATCH] unix/uxpoll: need _XOPEN_SOURCE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The code needs _XOPEN_SOURCE for some poll() flags.

Fix this build failure with uClibc:

./../unix/uxpoll.c: In function ‘pollwrap_add_fd_rwx’:
./../unix/uxpoll.c:75:32: error: ‘POLLRDNORM’ undeclared (first use in this function); did you mean ‘POLLNVAL’?
 #define SELECT_R_IN (POLLIN  | POLLRDNORM | POLLRDBAND)
                                ^
./../unix/uxpoll.c:87:19: note: in expansion of macro ‘SELECT_R_IN’
         events |= SELECT_R_IN;
                   ^~~~~~~~~~~
