    linux-libc-headers: update to 4.15.7
    
    While we don't normally follow all the -stable updates for libc-headers, there
    was one userspace header that was broken in the 4.15 cycle, and it has now
    been fixed in -stable.
    
    The offending header breaks the build for several packages, so we update to
    pick up this change:

           uapi/if_ether.h: move __UAPI_DEF_ETHHDR libc define
    
           commit da360299b6734135a5f66d7db458dcc7801c826a upstream.
    
           This fixes a compile problem of some user space applications by not
           including linux/libc-compat.h in uapi/if_ether.h.
    
           linux/libc-compat.h checks which "features" the header files, included
           from the libc, provide to make the Linux kernel uapi header files only
              provide no conflicting structures and enums. If a user application mixes
           kernel headers and libc headers it could happen that linux/libc-compat.h
           gets included too early where not all other libc headers are included
           yet. Then the linux/libc-compat.h would not prevent all the
           redefinitions and we run into compile problems.
           This patch removes the include of linux/libc-compat.h from
           uapi/if_ether.h to fix the recently introduced case, but not all as this
           is more or less impossible.
    
           It is no problem to do the check directly in the if_ether.h file and not
           in libc-compat.h as this does not need any fancy glibc header detection
           as glibc never provided struct ethhdr and should define
           __UAPI_DEF_ETHHDR by them self when they will provide this.
    
           The following test program did not compile correctly any more:
    
           #include <linux/if_ether.h>
           #include <netinet/in.h>
           #include <linux/in.h>
    
           int main(void)
           {
               return 0;
           }
    
           Fixes: 6926e041a892 ("uapi/if_ether.h: prevent redefinition of struct ethhdr")

    We also add a new muslc patch to adjust the ethhdr change in the uapi. As is
    suggested in the kernel commit, we can protect musl directly in if_ether itself.
