musl: fix handling of point-to-point interfaces in getifaddrs()
Current musl reports the peer (remote) address of a point-to-point interface and does not store the local address at all. Apply the same special treatment of IFA_LOCAL to musl's getifaddrs() which is also used in glibc and uclibc. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org> SVN-Revision: 47488
