Definitions of POLLWRNORM, POLLWRBAND and POLLREMOVE in xtensa linux
kernel are non-standard. Provide bits/poll.h with correct values for
these constants for uclibc-ng.
This fixes the following strace build errors:
In file included from xlat/pollflags.h:4:0,
from poll.c:34:
./static_assert.h:40:24: error: static assertion failed: "POLLWRBAND != 0x0100"
# define static_assert _Static_assert
^
xlat/pollflags.h:75:1: note: in expansion of macro ‘static_assert’
static_assert((POLLWRBAND) == (0x0100), "POLLWRBAND != 0x0100");
^~~~~~~~~~~~~
./static_assert.h:40:24: error: static assertion failed: "POLLREMOVE != 0x0800"
# define static_assert _Static_assert
