poll.h header should not be included from include/sys.  This works fine
on Glibc but fails on musl:

    In file included from tools/nciattach.c:42:
    /usr/include/sys/poll.h:1:2: error: #warning redirecting incorrect #include <sys/poll.h> to <poll.h> [-Werror=cpp]
        1 | #warning redirecting incorrect #include <sys/poll.h> to <poll.h>
