On Alpine Linux 3.9 (a musl libc system) there are compilation failures:

1) About the rcmd function, which musl libc apparently does not have:

2) About the <linux/if_ether.h>, which musl libc apparently does not have:

make[3]: Entering directory 
'/home/bruno/inetutils-1.9.4.50-9410/build-64/ifconfig'

          ^~~~~~~~~~~~~~~~~~
compilation terminated.

Both errors existed already in 1.9.4.
