* sysdeps/unix/sysv/linux/Dist: Add it. * sysdeps/unix/sysv/linux/Makefile [$(subdir)=socket] (headers): Add net/if.h. * Makeconfig (link-libc): Add libc.a after libc.so in link. * Rules (static-only-routines rule): Use empty.o instead of dummy.o. (empty.o): New target. (generated): Add empty.c, empty.o.
