linux-libc-headers: fix duplicate IFF_LOWER_UP DORMANT ECHO on musl
musl _does_ define IFF_LOWER_UP DORMANT ECHO so we should
prevent redefinition of these when on musl.
As per the included patch, this can be triggered by
(from connman 6to4.c):
include <errno.h>
include <stdio.h>
include <stdlib.h>
include <string.h>
include <sys/socket.h>
include <netinet/in.h>
include <arpa/inet.h>
include <net/if.h>
include <linux/ip.h>
include <linux/if_tunnel.h>
include <linux/netlink.h>
include <linux/rtnetlink.h>
include <sys/ioctl.h>
include <unistd.h>
In file included from ../git/src/6to4.c:34:0:
.../usr/include/linux/if.h:97:2: error: expected identifier before numeric constant
IFF_LOWER_UP = 1<<16, /* __volatile__ */
^
This is because at that time, IFF_LOWER_UP has been converted
to 0x10000 already:
enum net_device_flags {
0x10000 = 1<<16,
0x20000 = 1<<17,
0x40000 = 1<<18,
};
Backport a patch that addresses this.
